The enzyme characterised from Chrysanthemum segetum uses UDP-glucose to transfer a glucose unit to a specific phenolic hydroxy group of a flavonol, giving the corresponding flavonol 7-O-β-D-glucoside, with uridine diphosphate (UDP) as a byproduct. For example, quercetin is converted to quercimeritrin:[1]
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:flavonol 7-O-beta-D-glucosyltransferase. This enzyme is also called UDP-glucose:flavonol 7-O-glucosyltransferase.[2]
