Statistics of PiSITE
This version of PiSITE is based on the biological unit provided by RCSB Protein Data Bank as of March 2024. This database contains protein-protein interaction data for
- 367,855 protein chains
retrieved from
- 216,478 PDB entries
Distributions of protein-protein interactions
Distributions of protein-protein interactions in PiSITE were calculated from two datasets. The one is an 'all' dataset, including all protein chains in the PiSITE. The another is a 'nr (non-redundant)' dataset, including 22,654 protein chains with sequence identities < 30%. The list of non-redundant dataset can be obtained here. All graphs are for nr dataset.
Distributions of the number of binding states
Distributions of the number of binding partners
Amino acid frequency in the protein-protein interfaces
Amino acid occurrence of interacting residues
