Display the reaction diagram Show all sequences 2.1.1.283more the enzyme shows a broad substrate specificity. SpOMT7740 catalyzes the O-methylation reaction to form various natural and non-natural O-methoxides, includes 7-hydroxy-8-O-methoxy flavone, 3-O-methoxy flavone, three mono-, di-, and tri-O-methoxy genistein, mono-O-methoxy phloretin, mono-O-methoxy luteolin, 3-O-methoxy beta-sitosterol, and O-methoxy anthraquinones (emodin and aloe emodin) and O-methoxy anthracycline (daunorubicin) exhibiting diverse substrate flexibility. Mass spectrometric analysis of reaction products. 7,8-Dihydroxyflavone is the best substrate for bioconversion to 7-hydroxy-8-O-methoxy flavone. The enzyme seems to prefer methylation of hydroxy groups at C8 position. No or poor activity with doxorubicin and daunorubicin ? - ?
