DATA DEPOSITION

PDB Archive Version 3.15 Released

A new standardized version of the PDB archive will be available from ftp://ftp.wwpdb.org in early 2009. The date will be announced at wwpdb.org.

As of December 2, 2008, all new PDB releases follow PDB File Format Contents Guide Version 3.20. With the new version of the archive, all entries released prior to December 2, 2008 will be re-released as PDB Format Version 3.15 files. This release will overwrite all existing files.

A snapshot of the archive before this release will be available from ftp://snapshots.wwpdb.org/. Tools for downloading the archive can be found at www.wwpdb.org/downloads.html. For file format documentation, please see www.wwpdb.org/docs.html.

Questions may be sent to info@wwpdb.org.

Deposition Statistics

In the first quarter of 2009, 2041 experimentally-determined structures were deposited to the PDB archive. The entries were processed by wwPDB teams at the RCSB PDB, PDBe, and PDBj.

Of the structures deposited, 75.9% were deposited with a release status of "hold until publication"; 21.2% were released as soon as annotation of the entry was complete; and 2.9% were held until a particular date. 90.9% of these entries were determined by X-ray crystallographic methods; 8.5% were determined by NMR methods.

During the same time period, 1712 structures were released in the PDB.
