TDP-L-rhamnose–producing E. coli host containing Lamiales-derived UGT88D7 glycosyltransferase was employed to generate flavone rhamnosides and glucosides from apigenin, baicalein and luteolin. In comparison with the published literatures, this gene has showed markely flexible activity because it is able to transfer glucose, glucoronic acid and rhamnose moieties to aglycones. Although apigenin was manifested as the most favourite substrate baicalein and luteolin seemed to be good candidates to yield glycosylated products. The productivities of bioconversion of apigenin, baicalein and luteolin were 75.4, 36.1 and 32.4%, respectively, in the presence of methylated cyclodextrin as mediator. The formation of product was confirmed by TLC, HPLC and ESI-MS/MS measurement. The structural identification of products is being continued by NMR method. Data revealed the use of NDP-sugars flexible glycosyltransferase as an effective tool to produce various kinds of flavonoid glycosides by combinatorial biosynthesis in E. coli.
