IntEnz Enzyme Nomenclature
EC 2.4.1.234

Names

Accepted name:
kaempferol 3-O-galactosyltransferase
Other names:
F3GalTase
UDP-galactose:kaempferol 3-O-β-D-galactosyltransferase
Systematic name:
UDP-α-D-galactose:kaempferol 3-O-β-D-galactosyltransferase

Reaction

Comments:

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.
