3,7-dimethylquercetin 4'-O-methyltransferase


In enzymology, a 3,7-dimethylquercetin 4'-O-methyltransferase is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are S-adenosyl methionine and 5,3',4'-trihydroxy-3,7-dimethoxyflavone, whereas its two products are S-adenosylhomocysteine and 5,3'-dihydroxy-3,7,4'-trimethoxyflavone.
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:5,3',4'-trihydroxy-3,7-dimethoxyflavone 4'-O-methyltransferase. Other names in common use include flavonol 4'-O-methyltransferase, flavonol 4'-methyltransferase, 4'-OMT, S-adenosyl-L-methionine:3',4',5-trihydroxy-3,7-dimethoxyflavone, 4'-O-methyltransferase, and 3,7-dimethylquercitin 4'-O-methyltransferase .
