Flavonol-3-O-glucoside glucosyltransferase
From Wikipedia, the free encyclopedia
In enzymology, a flavonol-3-O-glucoside glucosyltransferase (EC 2.4.1.239) is an enzyme that catalyzes the chemical reaction
- UDP-glucose + a flavonol 3-O-beta-D-glucoside
UDP + a flavonol 3-O-beta-D-glucosyl-(1->2)-beta-D-glucoside
Thus, the two substrates of this enzyme are UDP-glucose and flavonol 3-O-beta-D-glucoside, whereas its two products are UDP and [[flavonol 3-O-beta-D-glucosyl-(1->2)-beta-D-glucoside]].
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:flavonol-3-O-glucoside 2-O-beta-D-glucosyltransferase.
