5 STEPS FOR CRYSTAL STRUCTURE DEPOSITION
At the ACA meeting, annotator Kyle Burkhardt presented a poster
entitled "Deposition and Annotation at the RCSB PDB". This poster
described 5 steps for depositing crystal structures:
1. Use the pdb_extract Program Suite (available on the Web and as a
2. Check your structure with the PDB Validation Suite (available on
the Web and as a software download)
3. Run BLAST (at NCBI - www.ncbi.nlm.nih.gov/BLAST)
4. Use Ligand Depot to identify and define your ligands
5. Deposit your structure using ADIT (available on the Web at
RCSB-US, PDBj, and as a software download)
A brochure that summarizes this poster is available from

PDB FOCUS: HOW ARE HPUB STRUCTURES RELEASED?
The release status of a structure is determined by the author at the
time of deposition. The status HPUB is used to indicate that a
structure will be released when the corresponding journal article is
published. Publication is considered to be when the article is
distributed by the publisher, either in print or electronically. The
RCSB emails the depositor to either confirm that the publication
corresponds to the structure, or to indicate that the structure will
be released because the article includes the PDB ID.
The RCSB PDB receives publication dates and citation information from
some journals. For other journals, the RCSB PDB scans the literature
for publication information. We also greatly appreciate the citation
information that is sent to us at firstname.lastname@example.org from the
PDB DEPOSITION STATISTICS
As of October 1, approximately 4128 structures have been deposited in
the PDB archive in 2004. Of the structures received, 77% were
deposited with a "hold until publication" release status; 13% with a
"release immediately" status; and 10% with a specific release date.
83% of these entries were the result of X-ray crystallographic
experiments; 14% were determined by NMR methods.
