PDB Statistics: Growth in Number of UniProtKB Entries with Known 3D Structure (Cumulative)

This chart shows the annual and cumulative numbers of unique UniProtKB entries in released PDB structures. The yearly bars (dark blue) tell how many new UniProtKB entries were added in a certain year.

Note: The total number of unique UniProtKB entries in the statistics table is linked to the group search result page. There is a default precision threshold in calculating the numbers for performance balance. So the statistics count may have a slight discrepancy compared to the actual non-redundant group search result when the result count approaches or goes above 10,000. The group search result page provides an accurate count. The statistics page provides the trend.
