coexpression of Oryza sativa ROMT-9, which methylates specifically at the 3'-hydroxyl group of quercetin and SOMT-2, which methylates at the 4'-hydroxyl group, in Escherichia coli. Reaction products of quercetin with the transformant show two methylation products that correspond to the 3'-methylated and the 3',4'-dimethylated quercetin. More than 90% of quercetin is converted into the 3',4'-dimethylated quercetin after 24 h incubation |
