PDB chemical components for NMR

The chemical components (ChemComp) information is updated weekly by wwPDB. For each new or updated chemical component a corresponding CCPN object is generated. The CCPN files are available from this page as well as from the CcpForge repository.

Enter a value in one of the fields below, then press the GO button, or click the Example button to prefill the form.

Three-letter code:
CCPN code: GO
Name: Example

Note: this page offers simple search options to look for a chemical compound in the CCPN repository. Use PDBeChem to do more complex searches (e.g. by supplying a SMILES string), then enter the three-letter code of the compound in the Three-letter code field above.
