Entry
EC 2.4.1.234                Enzyme                                 

Name
kaempferol 3-O-galactosyltransferase;
F3GalTase;
UDP-galactose:kaempferol 3-O-beta-D-galactosyltransferase
Class
Transferases;
Glycosyltransferases;
Hexosyltransferases
Sysname
UDP-alpha-D-galactose:kaempferol 3-O-beta-D-galactosyltransferase
Reaction(IUBMB)
UDP-alpha-D-galactose + kaempferol = UDP + kaempferol 3-O-beta-D-galactoside [RN:R06808]
Reaction(KEGG)
R06808
Substrate
UDP-alpha-D-galactose [CPD:C00052];
kaempferol [CPD:C05903]
Product
UDP [CPD:C00015];
kaempferol 3-O-beta-D-galactoside [CPD:C12626]
Comment
Acts on the endogenous flavonols kaempferol and quercetin, to a lesser extent on myricetin and fisetin, and weakly on galangin and isorhamnetin. The reaction can occur equally well in both directions.
