Term Name:	molybdopterin synthase complex
Synonyms:	molybdopterin cofactor (Moco) biosynthesis sulfurtransferase complex, MPT synthase complex
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.
