glucosylation occurs at the 4-coumarate moiety of the anthocyanin molecule cyanidin 3-O-[2-O-(2-O-(sinapoyl)xylosyl) 6-O-(p-coumaroyl) glucoside] 5-O-[6-O-(malonyl) glucoside] leading to completion of the main anthocyanin structure. Enzyme is more efficient with hydroxycinnamoyl-glucoses (C6-C3-glucoses) than benzoyl-glucose derivatives
