PDB Deposition Statistics

In 2003, 4,831 structures were deposited to the PDB archive, and were processed by teams at RCSB-Rutgers, Osaka University, and the European Bioinformatics Institute.

Of the structures deposited, 78% were deposited with a release status of "hold until publication"; 14% were released as soon as annotation of the entry was complete; and 8% were held until a particular date.

83% of these entries were determined by X-ray crystallographic methods; 13% were determined by NMR methods.

57% of these depositions released the sequence in advance of the structure's release. 72% of these depositions were deposited with experimental data.
