RCSBGraphQL Get Ligand Info

Get detailed chemical component (ligand) information from the PDB using the RCSB Data API. Returns the ligand name, molecular formula, molecular weight, SMILES, InChIKey, type (non-polymer, peptide-like, etc.), and known drug targets with their actions (inhibitor, substrate, cofactor, etc.) from DrugBank. Use this to look up small molecules, cofactors, or drugs found in PDB structures.
