Abstract: The glycosyltransferase UGT73B6 from Rhodiola sachalinensis with substrate flexibility can glycosylate many natural products catalyzed by UDP-glycosyltransferases(UGTs). To achieve the biosynthesis of phenolic compounds in Escherichia coli,in this study,we utilized the catalytic activity of the glycosyltransferase UGT73B6 and fed 7 different phenolic compounds in Escherichia coli BL21(DE3). By using biotransformation,we successfully achieved the biocatalysis of 8 glycoside compounds for the first time in Escherichia coli with UGT73B6,and further we explored the substrate flexibility of UGT73B6. On the basis of this study,we provided an effective and economical method to produce phenolic glycosides by microbial transformation,which has a great application value.
