2.4.1.240 | UDP-glucose + a flavonol 3-O-beta-D-glucosyl-(1->2)-beta-D-glucoside = UDP + a flavonol 3-O-beta-D-glucosyl-(1->2)-beta-D-glucosyl-(1->2)-beta-D-glucoside |
one of three specific glucosyltransferases in pea, Pisum sativum, that successively 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 |
