N2 - The organophosphorus pesticide hydrolase was purified to homogeneity from Burkholderia sp. NF100 by detergent extraction of the cell membrane fraction, anion-exchange, chromatofocusing, and gel filtration chromatographies. The purified enzyme had a molecular mass of 55 kDa and a pI 5.8, and the hydrolase activity was strongly inhibited by EDTA, dithiothreitol (DTT), Hg2+ and 1,10-phenanthroline. The optimum pH and temperature for the enzyme activity were 8.0 and 40°C, respectively. The enzyme hydrolyzed five organophosphorus pesticides.
