Pteridine reductase.
based on mapping to UniProt Q01782
5,6,7,8-tetrahydrobiopterin + 2 NADP(+) = biopterin + 2 NADPH.
-!- The enzyme from Leishmania (both amastigote and promastigote forms) catalyzes the NADPH-dependent reduction of folate and a wide variety of unconjugated pterins, including biopterin, to their tetrahydro forms. -!- It also catalyzes the reduction of 7,8-dihydropterins and 7,8- dihydrofolate to their tetrahydro forms. -!- In contrast to EC 1.5.1.3 and EC 1.5.1.34, pteridine reductase will not catalyze the reduction of the quinonoid form of dihydrobiopterin. -!- The enzyme is specific for NADPH; no activity has been detected with NADH. -!- It also differs from EC 1.5.1.3 in being specific for the B side of NADPH. -!- Formerly EC 1.1.1.253.
