Fig. 9From: Directed evolution and secretory expression of a pyrethroid-hydrolyzing esterase with enhanced catalytic activity and thermostabilityGas chromatography analysis of different pyrethroids hydrolyzed by M2. The red and black lines denote hydrolysis chromatography by inactive enzyme (control) and active enzyme, respectively. The enzyme solution were boiled for 20 min, and then centrifugated at 13,000g for 10 min. The supernatants were taken as inactive enzymesBack to article page
