In enzymology, a kaempferol 3-O-galactosyltransferase (EC 2.4.1.234) is an enzyme that catalyzes the chemical reaction

UDP-galactose + kaempferol $\rightleftharpoons$ UDP + kaempferol 3-O-beta-D-galactoside

Thus, the two substrates of this enzyme are UDP-galactose and kaempferol, whereas its two products are UDP and kaempferol 3-O-beta-D-galactoside.

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-galactose:kaempferol 3-O-beta-D-galactosyltransferase. This enzyme is also called F3GalTase.
