ENZYME entry: EC 1.1.1.219

Accepted Name
Dihydroflavanol 4-reductase.
Alternative Name(s)
Dihydroflavonol 4-reductase.
Dihydrokaempferol 4-reductase.
NADPH-dihydromyricetin reductase.
Reaction catalysed
A (2R,3S,4S)-leucoanthocyanidin + NADP(+) <=> a (2R,3R)-dihydroflavonol + NADPH
Comment(s)
  • This plant enzyme, involved in the biosynthesis of anthocyanidins, is known to act on (+)-dihydrokaempferol, (+)-taxifolin, and (+)- dihydromyricetin, although some enzymes may act only on a subset of these compounds.
  • Each dihydroflavonol is reduced to the corresponding cis-flavan-3,4- diol.
  • NAD(+) can act instead of NADP(+), but more slowly.
