2P2IDB is a hand-curated database dedicated to the structure of protein-protein complexes with known small molecule inhibitors. In the 2016 version of the database, we have gathered from the PDB, 26 PPIs and 242 small molecule inhibitors found at the interface (Basse et al., 2016).
Interfaces in 2P2IDB have been analyzed in terms of geometrical parameters, atom and residue properties, buried accessible surface area and other biophysical parameters and compared to those of representative datasets of heterodimeric complexes.
The 26 complexes have been classified into 3 classes based on the number of segments at the interface and target properties. Class 1 corresponds to protein-peptide complexes, Class 2 corresponds to globular protein-protein complexes and Class 3 corresponds to Bromodomain/Histone protein-protein complexes.
Since 2016, 2P2IDB is updated monthy.
The latest version (26-02-2020) contains 32 Protein-Protein complexes, 937 Protein-Ligand complexes and 828 PPI inhibitors.
The database is maintained by Marie-Jeanne Basse
