1.5.1.33 pteridine reductaseIUBMB Comments
The enzyme from Leishmania (both amastigote and promastigote forms) catalyses the reduction by NADPH of folate and a wide variety of unconjugated pterins, including biopterin, to their tetrahydro forms. It also catalyses the reduction of 7,8-dihydropterins and 7,8-dihydrofolate to their tetrahydro forms. In contrast to EC 1.5.1.3 (dihydrofolate reductase) and EC 1.5.1.34 (6,7-dihydropteridine reductase), pteridine reductase will not catalyse 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 (dihydrofolate reductase) in being specific for the Si-face of NADPH.

malfunction
-
comparisons of isogenic lines shows that ptr1-null mutants are 18fold more sensitive to H2O2 than PTR1-overproducing lines, and significant 3-5fold differences are seen with a broad panel of oxidant-inducing agents
malfunction
-
impossible to generate PTR1 null mutants. RNA interference results in complete knockdown of endogenous protein after 48 h, followed by cell death after 4 days. Lethal phenotype is reversed by expression of PTR1 in RNAi lines or by addition of tetrahydrobiopterin to cultures. Loss of PTR1 is associated with gross morphological changes due to a defect in cytokinesis, resulting in cells with multiple nuclei and kinetoplasts, as well as multiple detached flagella. Electron microscopy also reveal increased numbers of glycosomes, while immunofluorescence microscopy show increased and more diffuse staining for glycosomal matrix enzymes, indicative of mis-localisation to the cytosol. RNAi cell lines are markedly less virulent than wild-type parasites in mice
physiological function
-
using treatment with H2O2 as the selective pressure PTR1 is identified as a mediator of susceptibility to oxidative stress. Oxidant resistance depends upon reduced unconjugated pteridines and PTR1-derived pteridines can modulate oxidant susceptibility
physiological function
-
the enzyme has an essential and dual role in pterin metabolism
