Statistics of PiSITE
This version of PiSITE is based on
the biological unit

This database contains protein-protein interaction data for
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 7739 protein chains with sequence identities < 30%.
The list of non-redundant dataset can be obtained
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
