PDB Statistics: UniProtKB Entries with Known 3D Structure (Annual)
This chart shows the total number of unique UniProtKB entries in PDB structures released within each year.
Note: The 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.
