UDP-glucose:flavonol-3-O-beta-D-glucosyl-(1->2)-beta-D-glucoside 2'''-O-beta-D-glucosyltransferase

One of three specific glucosyltransferases in pea (Pisum sativum) thatsuccessively add a beta-D-glucosyl group first to O-3 of kaempferol, and then to O-2 of the previously added glucosyl group giving the 3-O-sophoroside and then the 3-O-sophorotrioside (see also EC 2.4.1.91 flavonol 3-O-glucosyltransferase, and EC 2.4.1.239 flavonol-3-O-glucoside glucosyltransferase).
