molybdopterin synthase complex

Function: - catalyzes the conversion of precursor Z into molybdopterin - acts by mediating the incorporation of 2 sulfur atoms from thiocarboxylated MOCS2A into precursor Z to generate a dithiolene group - cofactor biosynthesis; molybdopterin biosynthesis Structure: - heterotetramer - composed of 2 small (MOCS2A) & 2 large (MOCS2B) subunits (putative) Compartment: - cytoplasm, cytosol
