In enzymology a methylquercetagetin 6-O-methyltransferase (EC 2.1.1.84) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine + 563’4′-tetrahydroxy-37-dimethoxyflavone S-adenosyl-L-homocysteine + 53’4′-trihydroxy-367-trimethoxyflavoneThus the two substrates of this enzyme are S-adenosyl methionine and 563’4′-tetrahydroxy-37-dimethoxyflavone whereas its two products are S-adenosylhomocysteine and 53’4′-trihydroxy-367-trimethoxyflavone.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
