Happy Holidays from the PDB!

The PDB staff wish to extend our best wishes to the community for a happy holiday season and a wonderful new year!

17-Dec-2002

PDB Update Schedule for December 23-31

The PDB update that would normally occur on December 24 will instead take place on December 23. The update that would normally occur on December 31 will take place on December 30.

The regular PDB update schedule will resume with the January 7 update.

PDB to be Highlighted on New Jersey Network News

A segment highlighting the PDB will be shown as part of the New Jersey Network (NJN) News on Friday, December 27, 2002. The show will air at 6:00PM, 7:30PM, and 11:00PM on NJN Public Television (check your local listings for channel information) and at 5:30 PM on WNET/New York (Channel 13).

The news is also broadcast online at http://www.njn.net/television/webcast/.

10-Dec-2002

PDB CD-ROM Set #102 and Subsequent Releases

Issue 102 of the PDB CD-ROM sets is now shipping. With this release, 18,796 experimentally determined structures from the PDB FTP site as of October 1, 2002 are contained on a 5 CD-ROM set. The theoretical structures are also included in this set in a models directory.

The experimental data, X-ray structure factors and NMR constraints, are available as separate products for the structures for which they were deposited. For additional information and ordering instructions refer to the CD-ROM page at http://www.rcsb.org/pdb/cdrom.html.

The January 2003 release of the PDB CD-ROM sets, issue 103, will be a full release of experimentally determined structures. Starting with the April 2003 release an incremental set, structures released since the January 2003 release, will be sent to subscribers. Structures re-released for any reason will be included in the update.

July and October releases will be updates also. New subscribers will receive the January release and all subsequent updates. A list of files that have become obsolete since the last update will be sent with each release so users can update their set of structures.

The index files in the pub/resource sub-directory will continue to include all structures in the current PDB FTP site as of that release.

Experimental data, NMR constraints and X-ray structure factors, will be handled in the same manner as the structures - a complete set in January and incremental updates for the three subsequent quarters.

3-Dec-2002

New PDB Mirror Site in Germany

A new RCSB PDB mirror site has been established at the Max Delbr?ck Center for Molecular Medicine in Berlin, Germany. This site is now accessible at http://www.pdb.mdc-berlin.de/. A complete list of the RCSB PDB's eight worldwide mirror sites can be found at http://www.rcsb.org/pdb/mirrors.html.

26-Nov-2002

PDB Focus: Sequence Prerelease

PDB depositors are given the opportunity to prerelease a sequence in advance of the coordinates. ADIT's default setting is set to sequence prerelease.

From the PDB status search at http://www.rcsb.org/pdb/status.html, users may query all available sequences, or query based on criteria such as title or deposition date.

This feature was developed in response to requests made to the PDB. It is hoped that the prerelease of sequence data will prevent unintended duplication of effort in structure determination. It will allow users to conduct blind tests of structure prediction and modeling techniques.

Rsync Script for FTP Mirroring

An rsync script, rsyncPDB.sh, has been made available at ftp://ftp.rcsb.org/pub/pdb/software/. This script assists users in setting up their own local mirrors of the PDB FTP site. Before successfully running it, users will need to set three variables in rsyncPDB.sh to suit their local setup. The rsync script may be preferred to the mirror.pl script that was previously recommended for local mirroring of the FTP site. Questions about the rsync script may be sent to info@rcsb.org.

19-Nov-2002

PDB Annual Report 2002 Now Available

The PDB Annual Report 2002 is now being distributed. This document features a detailed look at the third full year of the operation of the PDB by Rutgers, the State University of New Jersey; the San Diego Supercomputer Center at the University of California, San Diego; and the Center for Advanced Research in Biotechnology of the National Institute of Standards and Technology -- three members of the RCSB. It highlights accomplishments during this period, from July 1, 2001 through June 30, 2002, and describes future developments of the PDB resource.

Requests for printed copies of the PDB Annual Report can be sent to AnnualReport@rcsb.org. This document is also available on-line in PDF format at http://www.rcsb.org/pdb/annual_report02.pdf.

PDB Art Exhibit part of CCMB's Silver Jubilee Celebrations and Symposium

The PDB's "Art of Science" exhibit will be part of the Centre for Cellular and Molecular Biology's (CCMB) Silver Jubilee Celebrations and Symposium on "The Current Excitement in Biology" in Hyderabad, India.

The exhibit will be on display at the CCMB campus's main building from November 15, 2002 through February 28, 2003. The Symposium (http://www.ccmb.res.in/symposium/) will take place November 24-29, 2002.

The PDB would like to see this exhibit travel to other places. If you would be interested in sponsoring this exhibit at your institution, please let us know at info@rcsb.org.

05-Nov-2002

BioEditor Now Available from the PDB Web Site

BioEditor, a program for creating and viewing structure presentations, is now accessible from the PDB Web site at http://www.rcsb.org/pdb/education.html#Other and http://www.rcsb.org/pdb/software-list.html#Graphics.

BioEditor (http://bioeditor.sdsc.edu/) is a tool to bridge the gap between printed literature and current Web-based presentation formats for macromolecular structures. It is a standalone Windows application that can be used to prepare and present structure annotations containing formatted text, graphics, sequence data, and interactive molecular views--all in a single document or set of documents. BioEditor facilitates the communication of structure data to a diverse audience by allowing users to create and view dynamic content in a uniform format that can be widely distributed through the internet.

BioEditor is designed to be used by structural scientists reporting and evaluating their data, as well as by educators and students who are seeking to relate structure to function in biological macromolecules. The BioEditor application includes features that enable the user to enter data, images, and references. Many features also link directly to resources on the internet.

Complete BioEditor documentaries on the PDB structures of a zinc binuclear cluster and the glyceraldehyde 3-phosphate dehydrogenase (GAPDH) enzyme are accessible from the Protein Documentaries section of PDB's Education Page at http://www.rcsb.org/pdb/education.html#Documentaries.

29-Oct-2002

Theoretical Models Search Interface on the PDB Beta Web Site

A simple search interface for theoretical model structures is now available from the PDB Beta Web Site at http://beta.rcsb.org/pdb/cgi/models.cgi. This interface facilitates searches by PDB ID, author, and compound, and is accessible from the top of the SearchLite and SearchFields interfaces. Feedback on this new feature may be sent to info@rcsb.org.

PDB Paper Published in Bioinformatics

The latest issue of Bioinformatics contains a paper describing the Ontology Driven Architecture that was developed to increase efficiency in the use of macromolecular structure (MMS) data contained in the PDB. The paper describes the OpenMMS Toolkit, a suite of software tools that conform to the OMG/LSR Corba standard (OMG specification formal/02-05-01). The OpenMMS Toolkit, is based on a metamodel architecture and is written entirely in Java. It contains an mmCIF parser, reference and database Corba servers, a relational database loader and a prototype XML formatted file converter. Detailed documentation and all of the source code are available at http://openmms.sdsc.edu.

Dihydrofolate Reductase, the Molecule of the Month for October, 2002.

PDB Focus: Educational Resources at the PDB

The "Educational Resources" page and the "Molecule of the Month" series are two important resources that the PDB maintains to serve the user community.

Each month, Dr. David S. Goodsell (The Scripps Research Institute) highlights a key biological molecule with illustrations and text designed for a general audience. These features are available from the PDB home page, and are archived at http://www.rcsb.org/pdb/molecules/molecule_list.html.

The PDB Educational Resources page at http://www.rcsb.org/pdb/education.html compiles molecular biology resources for audiences ranging from elementary level students to undergraduates to the general public. Proteins and nucleic acid tutorials, PDB articles and animations, protein documentaries, the World Index of Molecular Visualization Resources, and an illustrated glossary of crystallographic and NMR terminology are a few of the resources linked to from this page. Suggestions for additions to this page are appreciated and can be sent to info@rcsb.org.

24-Sep-2002

PDB Focus: PDBOBS

The PDBOBS database at http://pdbobs.sdsc.edu/index.cgi archives versions of PDB entries that have been obsoleted or superseded by more recent versions. These entries are made available for historical purposes, and to allow new versions of software to be tested against the same data sets as earlier versions of the software. The PDBOBS search interface can be used to locate obsolete entries by PDB ID or keyword. A list of obsolete PDB ID's is also available for browsing.

The result of all queries and the links in the browsing pages will graphically display the history of all versions of the PDB entry as well as a textual comparison of the key features of the structure.

A simple view of the sequence and backbone of any obsolete entry can be seen through the QuickPDB applet linked from the PDBOBS home page. This feature also includes a simple search by PDB ID capability. Content statistics and a list of enhancements are also accessible from the PDBOBS home page.

Obsolete PDB entries are also available from the FTP Web site at ftp://ftp.rcsb.org/pub/pdb/data/structures/obsolete/.

17-Sep-2002

CD-ROM News: Experimental Data To Be Offered as Separate CD-ROM Set

The number of entries in the PDB archive is ever-increasing, and this is reflected in the number of CD-ROMs required to contain each quarterly release. In order to reduce the number of disks in each set, beginning with the October 2002 CD-ROM release, subscribers will receive only the coordinate files for structure entries. This will include structures solved by X-Ray and NMR experimental techniques as well as those determined theoretically.

The experimental data files will no longer be included automatically. This will reduce the number of CD-ROMs to be loaded by 50%. Requests to receive either the X-Ray structure factors or NMR constraint files can be submitted at http://www.nist.gov/srd/o_nist801.htm.

All recipients of the current release, July 2002, received a flyer with the CD set that can be returned to request the experimental data as well as update their address. That same flyer is included as a README file on the first CD-ROM disk in directory pub and can thus be attached to an email to use in requesting the experimental data.

All CD-ROM services will continue to be available free of cost.

10-Sep-2002

Experimental Data Reporting and Model Access Enhancements

Enhancements have been made to the PDB site for reporting the availability of experimental data and for accessing model data.

The availability of experimental data for a particular structure can now be included in reports generated for a set of structures resulting from a PDB search. This new column indicates whether there is a structure factor or NMR restraint file available for each structure. This feature is included in the Structure Summary report and is offered as an option for the customizable reports. Tabular reports of results can be saved in HTML format or plain text format; the latter can also be imported into a spreadsheet program such as Excel.

Links to the models directory on the PDB FTP site (ftp://ftp.rcsb.org/pub/pdb/data/structures/models/) have been added to the SearchLite and SearchFields pages to facilitate access to these entries from the PDB Web site. This directory includes links to released theoretical model files, a set of index files containing the keyword, author, source organism, compound, resolution, crystal dimensions for these files, and the obsoleted theoretical model files.

Limited search capability for theoretical models will be made available in the near future.

03-Sep-2002

PDB Focus: Author Searches

Users can query for a particular author of a structure or a primary citation using the SearchFields interface at http://www.rcsb.org/pdb/cgi/queryForm.cgi. In the Citation Author field, enter the two initials and last name of the target author. An example of an author query would be:

S.S.Taylor
The initials should be separated by "."s without spaces between them or the last name. If the query is not formed this way, no results will be returned. For authors with a title included in their name, the format should be:
W.E.Royer Jr.
H.Brumer III

A search can also be performed using the author's last name only, for example:

Matthews
This will return all authors with the last name "Matthews" that are referenced in the PDB archive, as listed in the JRNL records or PDB REMARK 1 records in the structure entries. To remove a particular author from this result list, select the Refine Your Query option from the pull down menu at the top of the Query Result Browser page, which will return the SearchFields page. At the top, select the BUTNOT logic button and enter the author to be removed from the results list in the Citation Author field. For example:
B.W.Matthews
will remove all entries that reference "B.W.Matthews" from the "Matthews" result list.

Multiple authors can be queried for by performing a search for a single author as noted above, then selecting Refine Your Query from the pull down menu at the top of the results page, and entering the second author in the Citation Author field (note: the AND logic button on the SearchFields page must be selected, which is the default).

The Text Search field can also be used to query for part or all of one or more author names in a single query, such as:

Taylor and Zheng
However, users should be aware that this type of search scans the entire text of each PDB file and will return entries that include text that literally matches the query, so some undesired results may occur.

Requests for assistance with queries may be sent to info@rcsb.org.

This workshop organized by Helen Berman, Tom Terwilliger and John Westbrook was attended by more than forty people including software developers, people involved in data management for structural genomics projects, and representatives of the Protein Data Bank (PDB). The workshop focused on data specification, software integration, and data management issues associated with automated deposition of data into the PDB from high-throughput structure determinations.

The materials from this meeting have been made available at http://deposit.pdb.org/sgisi02/.

16-Jul-2002

New Features on the PDB Web Site

Three new features are now available from the primary PDB Web site and its mirror sites:

  • After a period of testing on the PDB beta Web site, the Swiss-Pdb Viewer is now linked from the View Structure section of the Structure Explorer page for each PDB entry.
  • The Citation Tabular Reports, which can provide bibliographic information for each structure in a search results set, now include links to search Medline either by PDB ID or Medline ID.
  • A Perl script to download PDB files from any given update date is now available from ftp://ftp.rcsb.org/pub/pdb/software/. This script has three usages:
    getPdbUpdate.pl dates -- retrieves and prints a list of valid update dates;
    getPdbUpdate.pl latest -- retrieves all files from the latest update; and
    getPdbUpdate.pl 20020603 -- retrieves all files from that particular update.

Questions or comments on these new features may be sent to info@rcsb.org.

02-Jul-2002

Target Registration Database Available for Structure Genomics Projects Worldwide

TargetDB is a target registration database that was originally developed to provide registration and tracking information for NIH P50 structural genomics centers. TargetDB has now been expanded to include target data from worldwide structural genomics and proteomics projects. The scope of TargetDB is to provide timely status and tracking information on the progress of the production and solution of structures.

The target database can be searched by sequence using FASTA (Pearson, W.R. and Lipman, D.J. (1988) "Improved tools for biological sequence comparison" PNAS 85:2444-2448). Sequence searches may include only the target sequences or the PDB sequences. Target sequences may also be searched by contributing site, protein name, project tracking identifier, date of last modification, and the current status of the target (e.g. cloned, expressed, crystallized, ...). Search results may be viewed as HTML reports, FASTA data files, or in XML.

Information on target classification is also available from http://presage.berkeley.edu and http://proteome.umbi.umd.edu.

25-Jun-2002

PDB Paper Published in American Scientist

As highlighted on its cover, the July-August issue 2002 of the American Scientist contains an article that explores the history of protein structure determination and the PDB. "Protein Structures: From Famine to Feast" also reports how structural genomics initiatives will populate the PDB with many unique structures in the future. The illustrations were created by David S. Goodsell, author and illustrator of the PDB's Molecule of the Month feature and Molecular Machinery poster.

Theoretical Model Files Soon to be Moved to Separate Directory on PDB FTP Site

As previously announced, the PDB will separate theoretical model coordinate files from the main archive beginning July 1, 2002. After this date, the main archive will consist of structures determined using experimental methods only. Theoretical models will only be available for download from the PDB FTP site as follows:

  • All theoretical models will be moved into a separate location in the FTP archive, and a subdirectory for obsoleted models will also become available:
    pub/pdb/data/structures/models/current
    pub/pdb/data/structures/models/obsolete
    Any newly deposited or released theoretical model will go directly into the /models/current directory. If it supersedes an earlier model, that earlier model will be obsoleted, and moved from /models/current to /models/obsolete.
  • Index files will be available in the models directories to facilitate browsing.
  • From the Web interfaces, a theoretical model file will only be accessible by entering its PDB ID. All other queries (SearchLite, SearchFields, Status) will not return model entries.
  • Searches by the PDB ID of a model through the Web will return a hyperlink to that model's coordinate file in the FTP archive.
  • Theoretical models will be removed from the PDB Contents Growth and PDB Holdings statistics at http://www.rcsb.org/pdb/holdings.html.

Theoretical models will also be moved to a separate location on the PDB CD-ROMs after July 1.

Models may still be deposited after this date, using ADIT: http://pdb.rutgers.edu/adit/, http://pdbdep.protein.osaka-u.ac.jp/adit/; or AutoDep: http://autodep.ebi.ac.uk/. These depositions will be forwarded to the models directory of the PDB FTP server without further annotation or validation.

Two PDB Papers Published

Two papers on the PDB resource have recently been published in a special issue of Acta Crystallographica on crystallographic databases.

A paper entitled, "The Protein Data Bank", was featured in this issue. This paper introduced and described the goals of the PDB, the systems in place for data deposition and access, and plans for the future development of the resource.

The article, "Protein structure resources", was also included in this periodical. In this article, web-accessible resources derived from data in the PDB were classified and described. These include resources for protein structure and functional classification, as well as links to primary genomic information, protein-protein interactions, protein dynamics, and protein-modeling resources.

PDB Focus: Query Result Browser Options

Any set of structures returned from a PDB search can be included in a tabular report, downloaded in one file, queried further in a refined search, and more when using the Query Result Browser.

The pull down menu at the top of the Query Result Browser page can be used to:

  • Perform a New Search -- returns either SearchFields or SearchLite, depending on which was used for the previous search.
  • Download Structures or Sequences -- search results can be downloaded in a single file in a variety of file and compression formats
  • Refine Your Query -- the resulting set can be searched further with the option to remove files that contain certain parameters or keywords
  • Create a Tabular Report -- choose from a variety of prepared reports (Structure Summary, Sequence, Crystallization Description, Unit Cell, Data Collection, Refinement, Citation) or customize your own
  • Select/Deselect All Structures -- all the entries can be selected/deselected with one click. This is useful when performing further operations on a result set in which the majority, but not all, structures are desired.
  • Remove Sequence Homologues -- creates a subset of the structures from which sequence homologues have been largely removed
  • Show Only Selected Structures -- removes unselected structures from the browser view
  • Show Structures on Hold -- returns a list of unreleased structures which match the query.
  • Review Your Query -- shows the search parameters used and the number of structures found, selected, and on hold.

These options are activated by selecting one and clicking on the "Go" button.

More information on using the options available from the Query Result Browser is available at http://www.rcsb.org/pdb/help-results.html.

PDB Focus: Restarting ADIT depositions

Depositing a structure using ADIT can be done in more than one session by using the "Session Restart ID". This identifier appears in red in the center of the browser window when the ADIT "deposit" step is first started. It also appears in the title of the browser throughout the deposition session.

ADIT stores the data entered in a category every time the user presses the SAVE button. These data will be available with the restart ID until the user deposits the entry by selecting the "DEPOSIT NOW" button.

The restart ID is entered in the space provided on the ADIT home page to return to the undeposited ADIT entry. Restart IDs are case-sensitive.

ADIT is available at http://deposit.pdb.org/adit/ (RCSB-US) and http://pdbdep.protein.osaka-u.ac.jp/adit/ (Osaka University, Japan).

A tutorial guide to using ADIT is available in English at http://pdb.rutgers.edu/adit/docs/tutorial.html and in Japanese at http://www.protein.osaka-u.ac.jp/pdb/. Example "in progress" ADIT depositions are available at http://pdb.rutgers.edu:81/.

Theoretical Model Coordinate Files to be Moved to Separate PDB FTP Directory

After much discussion with the user community over the last several years, and upon the recommendation of the PDB Advisory Committee, the PDB will separate theoretical models from the main archive. Beginning July 1, 2002, the main archive will consist of structures determined using experimental methods only. Theoretical models will be available for download from the PDB FTP site, and pointers to this location will be available from user query result summaries that include models in the result set. Theoretical models will also be moved to a separate location on the PDB CD-ROMs after July 1. Further details regarding the retrieval of models will be disseminated in the near future.

Models may still be deposited after this date using ADIT: http://pdb.rutgers.edu/adit/, http://pdbdep.protein.osaka-u.ac.jp/adit/; or AutoDep: http://autodep.ebi.ac.uk/. These depositions will be forwarded to the models directory of the PDB FTP server without further annotation or validation.

PDB Focus: Annotating Data Around the World

PDB data is processed by an international effort. ADIT deposition sites are located at the RCSB-Rutgers site (US) and at the Institute for Protein Research, Osaka University (Japan).

Structures deposited using ADIT are processed immediately and returned to the author. The files are fully processed and are released according to the release status provided by the author. Data are processed by staff from the RCSB (at Rutgers University in New Jersey and remotely at the Center for Complex Molecular Systems and Biomolecules in the Czech Republic) and from the Institute for Protein Research at Osaka University. The procedures used for processing these data are described in the PDB Data Processing and Annotation Procedures at http://www.rcsb.org/pdb/info.html#File_Formats_and_Standards.

Structures are also deposited using AutoDep at the European Bioinformatics Institute (EBI) in the United Kingdom. Data deposited using AutoDep are processed by the EBI.

Protein Art Proves to be Popular

"The Art of Science" opening reception at The Gallery
"The Art of Science" exhibit that displayed images from the Protein Data Bank, turned out to be one of the more popular shows held at The Gallery, a space dedicated to art exhibits at Rutgers University.

Many students, professors, and local educators viewed the exhibit during its run. Many commented on how they were surprised by how beautiful they found the images, and how interested they were in the scientific descriptions that accompanied the pictures. The exhibit also was the focus of several newspaper articles, including a story in The Star-Ledger and a front page article in The Bergen Record.

Various representations of proteins found in the PDB were highlighted, including large scale depictions of the images available from PDB Structure Explorer pages, images of collagen by Jordi Bella, and pictures from the PDB's Molecule of the Month series by David S. Goodsell. The exhibit, which was open from January 21 - February 9, was curated by Christine Zardecki.

Rate of PDB Holdings Growth Predicted in 1978?

In 1978, Richard E. Dickerson examined the number of available crystal structures. Based upon that number, he came upon an equation to describe the exponential growth for solved crystal structures.

In a letter describing a book he was working on with Irving Geis, Dickerson noted (and illustrated with a hand-drawn graph) that the number of new structures appeared to be following the exponential law n = exp(0.19 y), where n is the number of new structures per year and y is the year number since 1960. This equation predicted that at the end of 2001, there would be 13,941 crystal structure entries available in the PDB (14,000 crystal structures are currently available). Using this equation, there should be 24667 crystal structures in 2004.

Thanks to Arthur Arnone, who noticed that there were 57 structures more than Dickerson's equation predicted in March 2001. Predictions for the rate of NMR structures may be sent to info@rcsb.org.

Phase Out of BNL FTP Archive Reminder

Since 1999, the Research Collaboratory for Structural Bioinformatics (RCSB) has maintained two distinct FTP sites: the RCSB Protein Data Bank (PDB) site at ftp://ftp.rcsb.org/ (and its mirrors; see http://www.rcsb.org/pdb/mirrors.html), and the Brookhaven National Laboratory (BNL) PDB site at ftp://bnlarchive.rcsb.org.

In order to conserve resources and avoid confusion arising through the existence of two distinct PDB FTP sites, the RCSB will phase out the BNL PDB archive as of March 1, 2002, as announced on October 19, 2001 (http://www.rcsb.org/pdb/lists/pdb-l/200110/msg00024.html). This decision was made after consultation with the PDB Advisory Committee and review by members of the PDB user community.

The files previously available only at ftp://bnlarchive.rcsb.org/pub/resources/index/ are now available at ftp://ftp.rcsb.org/pub/pdb/derived_data/index/.

Current users of the BNL PDB archive are encouraged to consider the option of mirroring the RCSB FTP archive. The RCSB FTP archive can be found at ftp://ftp.rcsb.org and instructions for mirroring it can be found at http://www.rcsb.org/pdb/ftpproc.final.html.

A Perl script is provided to assist with conversion of existing BNL FTP directory structure to the RCSB FTP directory structure. Further information about the script is available at ftp://ftp.rcsb.org/pub/pdb/software/bnl2rcsb.pl.

Please send your questions or concerns, or requests for assistance regarding this change, to info@rcsb.org.

STING Millennium Suite Released on PDB Web Site

After a period of testing at the PDB beta test site, select components of STING Millennium Suite (SMS) are now available from the Structure Explorer pages of the primary PDB Web site and its mirrors. SMS, a set of Java-based tools for the simultaneous display of information about macromolecular structure and sequence, was developed by Dr. Goran Neshich of Embrapa-CNPTIA (Campinas, Brazil) and colleagues, in collaboration with Dr. Barry Honig's laboratory at Columbia University in New York City, NY. The SMS links from the PDB site are served by an SMS mirror that is being maintained at the San Diego Supercomputer Center.

The "Sequence Details" and "View Structure" sections of the Structure Explorer now link to two interactive structure and sequence SMS views for any PDB structure, which include options to access features such as a graphical display of amino acid contacts; these views require Chime and a Java-enabled Web browser. A simpler "Protein Dossier" view is also available from the "Sequence Details" section, offering a static graphical summary of sequence-and structure-based properties, such as relative entropy and temperature factors.

The "Geometry" section of the Structure Explorer now links to a Ramachandran plot for each PDB entry, also served from SMS, with options including the inter-connection of data in a dihedral angle plot with the 3-D structure of the molecule. This view also requires Java and Chime. SMS is also accessible from the "Other Sources" section of the Structure Explorer for each PDB entry, under the category of Visualization resources.

Further information about this suite of tools is available from the SMS home page at http://mirrors.rcsb.org/SMS/, and at http://www.rcsb.org/pdb/help-results.html. Comments may be sent to info@rcsb.org.

"The Art of Science" -- A PDB Art Gallery Exhibit

Images from the Protein Data Bank are being presented as "The Art of Science", an art exhibit appearing at Rutgers University that looks at the beauty inherent in the three-dimensional structures of proteins.

Various representations of proteins found in the PDB are highlighted, including large scale depictions of the images available from PDB Structure Explorer pages, images of collagen by Jordi Bella, and pictures from the PDB's Molecule of the Month series by David S. Goodsell. The exhibit was curated by Christine Zardecki.

"The Art of Science" is on display at The Gallery, a space dedicated to art exhibits at Rutgers University. The Gallery is located in the Busch Campus Center (604 Bartholomew Road, Piscataway, NJ). "The Art of Science" will be on display from January 21 - February 9, 2002 (Monday - Friday, 11AM to 10PM and Saturday - Sunday, 12PM to 4PM).
