Abstract
The enantioselectivity interaction of 2,4-dichlorprop (DCPP) and catalase were studied, and it was further evaluated with the presence of humus. Both of rac-DCPP and R-DCPP can inhibit the activity of catalase with the concentrations of 0.05–80 mg L−1, the inhibitory type of rac-DCPP was uncompetitive, and of R-DCPP was complex. The presence of humic acid has changed the inhibitory ability of DCPP on catalase, the inhibition of rac-DCPP disappeared and the inhibition type of R-DCPP mainly became uncompetitive. These results suggest that inhibition of chiral DCPP on catalase is enantioselective.
