Molybdopterin synthase (EC 2.8.1.12, MPT synthase) is an enzyme required to sythesize molybdenum cofactor (MoCo) from precursor Z (now known as cyclic pyranopterin monophosphate).[1][2] This enzyme catalyses the following chemical reaction

cyclic pyranopterin monophosphate + 2 [molybdopterin-synthase sulfur-carrier protein]-Gly-NH-CH2-C(O)SH + H2O molybdopterin + 2 molybdopterin-synthase sulfur-carrier protein

It is heterodimeric and coded for by the MOCS2 gene.[3]
