Enzyme Information

Anthocyanidin reductase ((2S)-flavan-3-ol-forming).
based on mapping to UniProt Q5FB34
(1) A (2S,3R)-flavan-3-ol + 2 NADP(+) = an anthocyanidin with a 3-hydroxy group + 2 NADPH. (2) A (2S,3S)-flavan-3-ol + 2 NADP(+) = an anthocyanidin with a 3-hydroxy group + 2 NADPH.
-!- The enzyme, characterized from Vitis vinifera (grape), participates in the flavonoid biosynthesis pathway. -!- It catalyzes the double reduction of anthocyanidins, producing a mixture of (2S,3S)- and (2S,3R)-flavan-3-ols. -!- The enzyme catalyzes sequential hydride transfers to C-2 and C-4, respectively. -!- Epimerization at C-3 is achieved by tautomerization that occurs between the two hydride transfers. -!- Cf. EC 1.3.1.77.
