| leucoanthocyanidin reductase | The enzyme catalyses the synthesis of catechin, catechin-4β-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. Group: Enzymes. Synonyms: leucocyanidin reductase. Enzyme Commission Number: EC 1.17.1.3. CAS No. 776323-46-7. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder.

| leucocyanidin oxygenase | The enzyme requires Fe(II) and ascorbate. It is involved in the pathway by which many flowering plants make anthocyanin (glycosylated anthocyandin) flower pigments.

Acidification of the products gives anthocyanidin, which, however, may not be a natural precursor of the anthocyanins. Group: Enzymes. Synonyms: anthocyanidin synthase.
