| Comment |
The anthocyanidin compounds cyanidin, delphinidin, peonidin and to a
lesser extent pelargonidin can act as substrates. The enzyme does
not catalyse glucosylation of the 5-position of cyanidin and does
not act on flavanols such as quercetin and kaempferol (cf. EC
2.4.1.91 flavonol 3-O-glucosyltransferase). In conjunction with EC
1.14.11.19, leucocyanidin oxygenase, 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 [3]. |
