The Gene Ontology^TM (GO) Consortium (PDF) is developing controlled vocabularies for describing gene products, applicable to all eukaryotes. The SIFTS initiative at the European Bioinformatics Institute has mapped PDB IDs and corresponding chain IDs to GO terms. Please note that not all PDB IDs/chains have been mapped to GO terms.

Here you can browse the GO molecular function hierarchy, view the number of associated PDB structures, and search for specific associated structures.
