Note:
  • The redundant data in single-chain format like BioLiP can be downloaded here.
  • The list of small molecules that are commonly used in protein structure determination can be downloaded here.
  • All DNA structures can be downloaded here.
  • All RNA structures can be downloaded here.
  • The script to convert between mmCIF format and PDB format can be downloaded here.
  • The 100 structures to validate DNA/RNA pairing algorithm can be downloaded here.
  • The Redundant receptor structures contains the receptor from all interactions (i.e. biological relevant + irrelevant interactions) and the structures with ligands or proteins only.
  • The Non-redundant version is based on biological relevant interactions.
