2,5-diamino-6-(ribozilamino)-4(3H)-pirimidinon 5'-fosfat reduktaza (EC 1.1.1.302, 2,5-diamino-6-ribozilamino-4(3H)-pirimidinon 5'-fosfatna reduktaza, MjaRED, MJ0671 (gen)) je enzim sa sistematskim imenom 2,5-diamino-6-(5-fosfo-D-ribozilamino)pirimidin-4(3H)-on:NAD(P)+ oksidoreduktaza.[1][2] Ovaj enzim katalizuje sledeću hemijsku reakciju
- 2,5-diamino-6-(5-fosfo-D-ribitilamino)pirimidin-4(3H)-on + NAD(P)+ 2,5-diamino-6-(5-fosfo-D-ribozilamino)pirimidin-4(3H)-on + NAD(P)H + H+
Reakcija teče u suprotnom smeru. Dejstvo ovog enzima je korak u riboflavinskoj biosintezi. NADPH i NADH funkcionišu jednako dobro kao reduktanti. Ovaj enzim se razlikuje od EC 1.1.1.193, 5-amino-6-(5-fosforibozilamino)uracil reduktaze, pošto on ne katalizuje redukciju 5-amino-6-ribozilaminopirimidin-2,4(1H,3H)-dion 5'-fosfata.
