GSH changes with time in the presence of purified LigF. In this part, the total volume of reaction mixture was 5 mL, the test group included 100 μL 20 mM GVG, 100 μL 3 mg/mL GSH,4300 μL 50 mM Tris–Cl (pH 8.0), 500 μL 10 μg/mL LigF. While in the control group, LigF was replaced by 500 μL 50 mM Tris–Cl buffer (pH 8.0). The reaction was carried out at 27 °C and 80 rpm. And then the equal volume of ethyl acetate was added to the reaction mixture to stop the enzymatic reaction. The mixture was centrifuged for 2 min at 13000 rpm and 50 μL water phase was taken for the GSH content analysis to describe the LigF activity
