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 software download)

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 http://deposit.pdb.org/xtal-struct-dep.pdf.

These steps utilize RCSB PDB data deposition tools available from deposit.pdb.org/depoinfo/depotools.html

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 deposit@rcsb.rutgers.edu from the community.

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.
