Thus, 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. The systematic name of this enzyme class is S-adenosyl-L-methionine:kaempferol 4'-O-methyltransferase. Other names in common use include S-adenosyl-L-methionine:flavonoid 4'-O-methyltransferase, and F 4'-OMT.
