ENZYME entry: EC 2.4.1.239
Accepted Name |
Flavonol-3-O-glucoside glucosyltransferase.
|
Reaction catalysed |
UDP-glucose + a flavonol 3-O-beta-D-glucoside <=> UDP + a flavonol 3-O-beta-D-glucosyl-(1->2)-beta-D-glucoside |
Comment(s) |
- 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 and EC 2.4.1.240).
- TDP-glucose can replace UDP-glucose as the glucose donor but the
reaction proceeds more slowly.
