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

More general terms

• molecular complex
