Flavonol-3-O-glycoside xylosyltransferase

UDP-D-xylose + a flavonol 3-O-glycoside $rightleftharpoons$ UDP + a flavonol 3-[-D-xylosyl-(1->2)-beta-D-glycoside]

Thus, the two substrates of this enzyme are UDP-D-xylose and flavonol 3-O-glycoside, whereas its two products are UDP and flavonol 3-[-D-xylosyl-(1->2)-beta-D-glycoside].

This enzyme belongs to the family of glycosyltransferases, specifically the pentosyltransferases. The systematic name of this enzyme class is UDP-D-xylose:flavonol-3-O-glycoside 2''-O-beta-D-xylosyltransferase.
