ANTHOCYANIDIN SYNTHASE FROM ARABIDOPSIS THALIANA COMPLEXED WITH TRANS-DIHYDROQUERCETIN
Overview
Flavonoids are common colorants in plants and have long-established, biomedicinal properties. Anthocyanidin synthase (ANS), a 2-oxoglutarate, iron-dependent oxygenase, catalyzes the penultimate step in the, biosynthesis of the anthocyanin class of flavonoids. The crystal structure, of ANS reveals a multicomponent active site containing metal, cosubstrate, and two molecules of a substrate analog (dihydroquercetin). An additional, structure obtained after 30 min exposure to dioxygen is consistent with, the oxidation of the dihydroquercetin to quercetin and the concomitant, decarboxylation of 2-oxoglutarate to succinate. Together with in vitro, studies, the crystal structures suggest a mechanism for ANS-catalyzed, anthocyanidin formation from the natural leucoanthocyanidin substrates, ... [(full description)]
