Enzyme activity analysis of TaUGT6 in DON glucosylation. GST or GST-tagged TaUGT6 proteins were added to the reaction mixture with UDP-glucose as the sugar donor and DON as the substrate and analyzed using HPLC–MS/MS. HPLC–MS/MS analysis of the DON standard substance (A) and DON-3-O-glucoside standard substance (B). HPLC–MS/MS analysis of DON (C) and D3G (D) in the reaction mixture with GST after 3 hours reaction. The reaction mixture with GST-tagged TaUGT6 proteins after 3 hours reaction was analyzed, and DON (E) and D3G (F) were detected.
