General Information
Term molybdopterin synthase complex ID (Ontology) GO:1990140 (Gene Ontology)
Definition A heterotetrameric protein complex that catalyses sulfur transfer from the sulfur carrier subunit of molybdopterin synthase to precursor Z to synthesize molybdopterin as part of molybdopterin cofactor (Moco) biosynthesis. In E. coli the subunits are MoaE and MoaD; in human, MOCS2B and MOCS2A. Moco biosynthesis and its constituent molecules are evolutionarily conserved.[ PubMed:11135669 PubMed:16669776 ]
Also Known As "molybdopterin converting factor complex" ; "MPT synthase complex"
