In enzymology, an apigenin 4'-O-methyltransferase () is an enzyme that catalyzes the chemical reaction :S-adenosyl-L-methionine + 5,7,4'-trihydroxyflavone S-adenosyl-L-homocysteine + 4'-methoxy-5,7-dihydroxyflavone Thus, the two substrates of this enzyme are S-adenosyl methionine and 5,7,4'-trihydroxyflavone (apigenin), whereas its two products are S-adenosylhomocysteine and 4'-methoxy-5,7-dihydroxyflavone (acacetin). 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:5,7,4'-trihydroxyflavone 4'-O-methyltransferase. Other names in common use include flavonoid O-methyltransferase, and flavonoid methyltransferase. This enzyme participates in flavonoid biosynthesis. == References == * 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Apigenin 4'-O-methyltransferase」の詳細全文を読む スポンサード リンク
