Biological Peptide-protein complex structures
PepBDB collected all the biological complex structures of peptide-mediated protein interactions
with peptide lengths up to 50 residues
in the Protein Data Bank. A valid PepBDB record is a peptide-protein complex where the peptide
directly binds to at least one protein chain. PepBDB used the biological
units when searching the complexes meeting the criteria. The pdb files were carefully processed to obtain
cleaned peptide-protein complex structures and binding residues.
The database presents extensive information about biological peptide-mediated protein interactions.
PepBDB allows users to search the database by a variety of options including sequences and
interactively visualize the peptide-protein complex structures and interactions.
The database is updated monthly to include new data released in the PDB.
