ID   2.4.1.239
DE   flavonol-3-O-glucoside glucosyltransferase.
CA   a flavonol 3-O-beta-D-glucoside + UDP-alpha-D-glucose = a flavonol 3-O-
CA   beta-D-glucosyl-(1->2)-beta-D-glucoside + H(+) + UDP.
CC   -!- One of three specific glucosyltransferases in pea (Pisum sativum)
CC       that successively add a beta-D-glucosyl group first to O-3 of
CC       kaempferol, and then to O-2 of the previously added glucosyl group
CC       giving the 3-O-sophoroside and then the 3-O-sophorotrioside (see also
CC       EC 2.4.1.91 and EC 2.4.1.240).
CC   -!- TDP-glucose can replace UDP-glucose as the glucose donor but the
CC       reaction proceeds more slowly.
