In enzymology a kaempferol 4′-O-methyltransferase (EC 2.1.1.155) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine + kaempferol S-adenosyl-L-homocysteine + kaempferideThus the two substrates of this enzyme are S-adenosyl methionine and kaempferol whereas its two products are S-adenosylhomocysteine and kaempferide.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
