ENZYME entry: EC 1.17.1.3

Accepted Name
Leucoanthocyanidin reductase.
Alternative Name(s)
Leucocyanidin reductase.
Reaction catalysed
(2R,3S)-catechin + NADP(+) + H(2)O <=> 2,3-trans-3,4-cis-leucocyanidin + NADPH
Comment(s)
  • Catalyzes the synthesis of catechin, catechin-4-beta-ol (leucocyanidin) and the related flavan-3-ols afzelechin and gallocatechin, which are initiating monomers in the synthesis of plant polymeric proanthocyanidins or condensed tannins.
  • While 2,3-trans-3,4-cis-leucocyanidin is the preferred flavan-3,4- diol substrate, 2,3-trans-3,4-cis-leucodelphinidin and 2,3-trans-3, 4-cis-leucopelargonidin can also act as substrates, but more slowly.
  • NADH can replace NADPH but is oxidized more slowly.
