CC -!- FUNCTION: Exhibits a NADPH-dependent biopterin reductase activity. Has
CC good activity with folate and significant activity with dihydrofolate
CC and dihydrobiopterin, but not with quinonoid dihydrobiopterin. Confers
CC resistance to methotrexate (MTX). {ECO:0000269|PubMed:7972081}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(6R)-L-erythro-5,6,7,8-tetrahydrobiopterin + 2 NADP(+) = 2
CC H(+) + L-erythro-biopterin + 2 NADPH; Xref=Rhea:RHEA:19509,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349,
CC ChEBI:CHEBI:59560, ChEBI:CHEBI:63931; EC=1.5.1.33;
CC -!- PATHWAY: Cofactor biosynthesis; tetrahydrobiopterin biosynthesis;
CC tetrahydrobiopterin from biopterin: step 1/1.
CC {ECO:0000269|PubMed:9521731}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000269|PubMed:11373620,
CC ECO:0000269|PubMed:9153248}.
CC -!- SIMILARITY: Belongs to the short-chain dehydrogenases/reductases (SDR)
CC family. {ECO:0000305}.
