KEGG   ENZYME: 2.4.1.239
Entry
EC 2.4.1.239                Enzyme                                 
Name
flavonol-3-O-glucoside glucosyltransferase;
UDP-glucose:flavonol-3-O-glucoside 2''-O-beta-D-glucosyltransferase
Class
Transferases;
Glycosyltransferases;
Hexosyltransferases
Sysname
UDP-glucose:flavonol-3-O-beta-D-glucoside 2''-O-beta-D-glucosyltransferase
Reaction(IUBMB)
UDP-glucose + a flavonol 3-O-beta-D-glucoside = UDP + a flavonol 3-O-beta-D-glucosyl-(1->2)-beta-D-glucoside [RN:R07339]
Reaction(KEGG)
R07339 > R06804 R06812
Substrate
UDP-glucose [CPD:C00029];
flavonol 3-O-beta-D-glucoside [CPD:C03946]
Product
UDP [CPD:C00015];
flavonol 3-O-beta-D-glucosyl-(1->2)-beta-D-glucoside [CPD:C15581]
Comment
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 2.4.1.240, flavonol-3-O-glycoside glucosyltransferase). TDP-glucose can replace UDP-glucose as the glucose donor but the reaction proceeds more slowly.
