ENZYME entry: EC 2.4.1.115

Accepted Name
Anthocyanidin 3-O-glucosyltransferase.
Alternative 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.
Reaction catalysed
UDP-D-glucose + an anthocyanidin <=> UDP + an anthocyanidin-3-O-beta-D-glucoside
Comment(s)
  • 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 1.14.20.4, 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.
