PDB Statistics: Unique Number of Domains (SCOP/SCOPe, ECOD, SCOP, CATH) in Released PDB Structures (Annual)

Select SCOP/SCOPe, ECOD, or CATH to show the number of unique domains added by the resource in each year. All classifications may be displayed simultaneously.

Please note that some of the resources (e.g. CATH) may be lagging behind the PDB, so data for the last year might be undercounting the number of domains in the PDB.
