Molibdopterin sintaza (EC 2.8.1.12, MPT sintaza) je enzim sa sistematskim imenom tiokarboksilisana molibdopterin sintaza:ciklična piranopterin monofosfat sumportransferaza.[1][2] Ovaj enzim katalizuje sledeću hemijsku reakciju
- ciklični piranopterin monofosfat + 2 [molibdopterin-sintaza sumpor-nosilac protein]-Gly-NH-CH2-C(O)SH +H2O molibdopterin + 2 molibdopterin-sintaza sumpor-nosilac protein
Ovaj enzim katalizuje sintezu molibdopterina iz cikličnog piranopterin monofosfata.
