PDB Statistics: Growth in Number of Domains in Released PDB Structures (Cumulative)
Select SCOP/SCOPe, ECOD, or CATH to show the number of unique domains added in a year (dark blue) and total domains available (light blue).
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.
