In this study, three glycosyltransferases involved in the biosynthesis of a complex acylated phenolic glycoside in Ligustrum robustum were characterized. These enzymes expand the toolbox for synthesizing natural products with various sugar chains.
In this study, we report the characterization of three glycosyltransferases involved in the biosynthesis of ligupurpuroside B, a complex acylated phenolic glycoside in Ligustrum robustum. UGT85AF8 catalyzed the formation of salidroside from tyrosol. UGT79G7, an osmanthuside A 1,3-rhamnosyltransferase, and UGT79A19, an osmanthuside B 1,4-rhamnosyltransferase, sequentially converted osmanthuside A into ligupurpuroside B. Orthologs of UGT79G7 were also discovered from other plants producing verbascoside. These rhamnosyltransferases expand the toolbox for the biosynthesis of natural products with various sugar chains.
