Flavonol-3-O-glycoside xylosyltransferase

Flavonol-3-O-glycoside xylosyltransferase

In enzymology, a flavonol-3-O-glycoside xylosyltransferase (EC number| is an enzyme that catalyzes the chemical reaction

:UDP-D-xylose + a flavonol 3-O-glycoside ightleftharpoons 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.
