Abstract

A carbaryl hydrolase was purified to homogeneity from Arthrobacter sp. strain RC100 by protamine sulfate treatment, ammonium sulfate precipitation, and hydrophobic, anion-exchange, and gel filtration chromatographies. The native enzyme had a molecular mass of 100 kDa and was composed of two identical subunits with molecular masses of 51 kDa. The hydrolase activity was strongly inhibited by DIFP, PMSF, Hg2+ and paraoxon but not by EDTA. The optimum pH and temperature for the enzyme activity were 9.0 and 50°C, respectively. The enzyme hydrolyzed four N-methylcarbamate insecticides (carbaryl, xylylcarb, metolcarb and XMC), but was not able to hydrolyze fenobucarb, propoxur, and isoprocarb.
