PDB Deposition and Growth Statistics for 2001

In 2001, 3,298 structures were deposited to the PDB, and were processed by teams at RCSB-Rutgers (75%), Osaka University (10%), and the European Bioinformatics Institute (14%).

Of the structures deposited, 72% were deposited with a release status of "hold until publication"; 16% were released as soon as annotation of the entry was complete; and 12% were held until a particular date. 82% of these entries were determined by X-ray crystallographic methods; 15% were determined by NMR methods.

The growth of the PDB can be seen in the increase in the number of residues added into the archive each year. 1,680,053 residues were released into the archive in 2001, as compared to 1,314,912 in 2000 and 1,068,340 in 1999.
