ID 1.1.1.219 DE dihydroflavanol 4-reductase. AN dihydroflavonol 4-reductase. AN dihydrokaempferol 4-reductase. AN NADPH-dihydromyricetin reductase. CA a (2R,3S,4S)-leucoanthocyanidin + NADP(+) = a (2R,3R)-dihydroflavonol + CA H(+) + NADPH. CC -!- This plant enzyme, involved in the biosynthesis of anthocyanidins, CC is known to act on (+)-dihydrokaempferol, (+)-taxifolin, and (+)- CC dihydromyricetin, although some enzymes may act only on a subset of CC these compounds. CC -!- Each dihydroflavonol is reduced to the corresponding cis-flavan-3,4- CC diol. CC -!- NAD(+) can act instead of NADP(+), but more slowly.
