BRITE hierarchy
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)
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.
