additional information | generation of a multifunctional FOMT fusing a 3'-OMT (SlOMT3, EC 2.1.1.267) and a 7-OMT (OsNOMT, EC 2.1.1.82). The SlOMT3/OsNOMT fusion enzyme possesses both 3'- and 7-OMT activities to diverse flavonoid substrates, which are comparable to those of individual SlOMT3 and OsNOMT. The SlOMT3/OsNOMT enzyme also shows 3'- and 7-OMT activity for 7- or 3'-O-methylflavonoids, respectively, suggesting that the fusion enzyme can sequentially methylate flavonoids into di-O-methylflavonoids. The biotransformation of the flavonoids quercetin, luteolin, eriodictyol, and taxifolin using SlOMT3/OsNOMT-transformed Escherichia coli generated corresponding di-O-methylflavonoids, rhamnazin, velutin, 3',7-di-O-methyleriodictyol, and 3',7-di-O-methyltaxifolin, respectively. These results indicate that dimethoxyflavonoids may be efficiently produced from non-methylated flavonoid precursors through a one-step biotransformation using the engineered Escherichia coli harboring the SlOMT3/OsNOMT fusion gene | Oryza sativa |
