Accepted name: |
kaempferol 3-O-galactosyltransferase |
Reaction: |
UDP-α-D-galactose + kaempferol = UDP + kaempferol 3-O-β-D-galactoside |

Other name(s): |
F3GalTase; UDP-galactose:kaempferol 3-O-β-D-galactosyltransferase |
Systematic name: |
UDP-α-D-galactose:kaempferol 3-O-β-D-galactosyltransferase |
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. |
