Registry Chemical Component Dictionary

The Chemical Component Dictionary is as an external reference file describing all residue and small molecule components found in Protein Data Bank entries. It contains detailed chemical descriptions for standard and modified amino acids/nucleotides, small molecule ligands, and solvent molecules. Each chemical definition includes descriptions of chemical properties such as stereochemical assignments, aromatic bond assignments, idealized coordinates, chemical descriptors (SMILES & InChI), and systematic chemical names.

Comment might be same as pdb.ligand, not sure though

The metaregistry provides mappings between the Bioregistry and other registries. There are 3 mappings to external registries for pdb-ccd.

Registry Name Metaprefix External Prefix miriam pdb-ccd
Name-to-Thing n2t pdb-ccd
Prefix Commons prefixcommons PDB-CCD

Providers are various services that resolve CURIEs to URLs. The example CURIE pdb-ccd:AB0 is used to demonstrate the provides available for pdb-ccd. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
