Enzyme Information
| 1.1.1.219 |
Dihydroflavanol 4-reductase.
based on mapping to UniProt P51110
A (2R,3S,4S)-leucoanthocyanidin + NADP(+) = a (2R,3R)-dihydroflavonol + NADPH.
-!- 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.
|
| 1.1.1.234 |
Flavanone 4-reductase.
based on mapping to UniProt P51110
(2S)-flavan-4-ol + NADP(+) = (2S)-flavanone + NADPH.
-!- Involved in the biosynthesis of 3-deoxyanthocyanidins from flavanones such as naringenin or eriodictyol.
