The PDBOBS database at
archives versions of PDB entries that have been obsoleted or superseded by more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
