FunFam 291911: Pteridine reductase 1

There are 6 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Pteridine reductase. [EC: 1.5.1.33]
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.

Thymidylate synthase. [EC: 2.1.1.45]
5,10-methylenetetrahydrofolate + dUMP = dihydrofolate + dTMP.
    		 8 A0A088SA10 A0A088SA10 A4HCP1 A4HCP1 A4I067 A4I067 E9BG51 E9BG51
    Dihydrofolate reductase. [EC: 1.5.1.3]
    5,6,7,8-tetrahydrofolate + NADP(+) = 7,8-dihydrofolate + NADPH.
    • The enzyme from animals and some micro-organisms also slowly reduces folate to 5,6,7,8-tetrahydrofolate.
    • Formerly EC 1.5.1.4.
    		 6 A4HCP1 A4HCP1 A4I067 A4I067 E9BG51 E9BG51
    3-oxoacyl-[acyl-carrier-protein] reductase. [EC: 1.1.1.100]
    (3R)-3-hydroxyacyl-[acyl-carrier-protein] + NADP(+) = 3-oxoacyl-[acyl- carrier-protein] + NADPH.
    • Exhibits a marked preference for [acyl-carrier-protein] derivatives over CoA derivatives as substrates.
    		 4 A0A0F4Z0E1 A0A0F4Z0E1 A2QQB6 A2QQB6
    6,7-dihydropteridine reductase. [EC: 1.5.1.34]
    A 5,6,7,8-tetrahydropteridine + NAD(P)(+) = a 6,7-dihydropteridine + NAD(P)H.
    • The substrate is the quinonoid form of dihydropteridine.
    • Not identical with EC 1.5.1.3.
    • Formerly EC 1.6.99.7 and EC 1.6.99.10.
    		 2 A0A088SA10 A0A088SA10
    L-xylulose reductase. [EC: 1.1.1.10]
    Xylitol + NADP(+) = L-xylulose + NADPH.
