Over 800 structures were deposited to the PDB in the first quarter of the year 2001. Among all of these many interesting structures, we received seven structures of ribosomal subunits, as well as the complete Thermus thermophilus 70S ribosome structure.
Approximately 64% of all of the structures received during this period were deposited with a "hold until publication" release status; 21% were deposited with a specific hold date; and 14% were deposited with a "release immediately" status. 83% were the result of X-ray crystallographic experiments; 14% from NMR.
Structures may be deposited using ADIT at http://pdb.rutgers.edu/adit/ (at the RCSB-Rutgers site) or at http://pdbdep.protein.osaka-u.ac.jp/adit/ (at the Institute for Protein Research at Osaka University, Japan). AutoDep is also available for PDB depositions at the EBI at http://autodep.ebi.ac.uk/. The RCSB also maintains a copy of AutoDep at http://pdb.rutgers.edu/~adbnl/.
