activated the p-nitrophenyl acetateand p-nitrophenyl butyrate-hydrolysing activity of sheep serum at a significantly slower rate than it did the paraoxon-hydrolysing activity. From this and supporting evidence involving theKm for hydrolysis activity of sheep, rabbit and hog sera and of purified paraoxonase towards p-nitrophenyl acetate, it was concluded that a new esterase hydrolysing pnitrophe...
