About CovPDB

CovPDB is a freely accessible web database solely dedicated to high-resolution 3D structures of biologically relevant covalent protein–ligand complexes, mined from the Protein Data Bank ( https://www.rcsb.org/ ).

We have so created CovPDB to assist structure-based approaches in chemical biology and drug design by identifying covalent binding sites suitable for the docking of drug-like ligands, and, likewise, typical ligands that covalently modifying targetable binding sites. Furthermore, the corresponding covalent bonding mechanisms of such complexes were manually expertly annotated. Totally, CovPDB describes:

  • 2294 covalent complexes
  • 1501 pre-reactive ligands
  • 733 target proteins
  • 93 reactive warheads
  • 21 covalent mechanisms
  • 14 targetable residues

CovPDB freely provides its content as separate files for download, namely, all ligand structures (SDF format), protein sequences (FASTA format), protein-ligand complexes (PDB format), and reactive warheads (TXT format).
