EC | 1.3.1.112 | ||||
Accepted name: | anthocyanidin reductase [(2S)-flavan-3-ol-forming] | ||||
Reaction: | (1) a (2S,3R)-flavan-3-ol + 2 NADP+ = an anthocyanidin with a 3-hydroxy group + 2 NADPH + H+ (2) a (2S,3S)-flavan-3-ol + 2 NADP+ = an anthocyanidin with a 3-hydroxy group + 2 NADPH + H+ |
||||
Systematic name: | (2S)-flavan-3-ol:NAD(P)+ oxidoreductase | ||||
Comments: | The enzyme, characterized from Vitis vinifera (grape), participates in the flavonoid biosynthesis pathway. It catalyses the double reduction of anthocyanidins, producing a mixture of (2S,3S)- and (2S,3R)-flavan-3-ols. The enzyme catalyses 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, anthocyanidin reductase [(2R,3R)-flavan-3-ol-forming]. | ||||
