Glycosylation is one of major modifications for plant secondary metabolites. In the case of volatile compounds, glycosylation makes them nonvolatile and odorless. Identification of UDP-dependent glycosyltransferases responsible for volatile glycosylation is essential to understand the regulatory mechanism of volatile release from plant tissues. Here, we describe an efficient protocol to find possible combinations of volatiles/glycosyltransferases using tomato (Solanum lycopersicum) enzymes expressed in Escherichia coli. The presented method requires a basic gas chromatography system and conventional laboratory tools.
