Abstract excerpt
Evidence is presented that human serum contains a single enzyme with both paraoxonase and arylesterase activities. Throughout the steps of purification and after obtaining over 600-fold purification of the enzyme, the arylesterase activity (measured with phenylacetate as the substrate) co-eluted and retained the same ratio of activity to paraoxonase activity as it had in the initial plasma sample. Paraoxon and...
