Other name(s): 3-GT. UDP-glucose:anthocyanidin 3-O-D-glucosyltransferase. UDP-glucose:anthocyanidin/flavonol 3-O-glucosyltransferase. UDP-glucose:cyanidin-3-O-glucosyltransferase. Uridine diphosphoglucose-anthocyanidin 3-O-glucosyltransferase.
Comments: The anthocyanidin compounds cyanidin, delphinidin, peonidin and to a lesser extent pelargonidin can act as substrates. Does not catalyze glucosylation of the 5-position of cyanidin and does not act on flavanols such as quercetin and kaempferol (cf. Ec 2.4.1.91). In conjunction with Ec 1.14.11.19, it is involved in the conversion of leucoanthocyanidin into anthocyanidin 3-glucoside. It may act on the pseudobase precursor of the anthocyanidin rather than on the anthocyanidin itself. Formerly Ec 2.4.1.233.
