PDB Statistics: Growth in Number of Protein Sequences in Released PDB Structures (Cumulative) at identity 30%

This chart shows the annual and cumulative numbers of protein sequences in released PDB structures. The chart can be viewed for a few different levels of sequence identity since the beginning of the PDB archive. The cumulative bars represent the growth in unique protein sequences (number of polymeric entities) across history. The yearly bars (dark blue) tell how many new protein sequences were added in a certain year.
