A-esterase, more popularly known as paraoxonase (EC, is a family of enzymes, one of which breaks down the toxic, metabolically activated oxygen analogs of a handful of organophosphorus insecticides and nerve gases. Paraoxonase probably plays a role in the detoxification of these chemicals at high exposure levels, but likely is less important than other detoxification pathways following low insecticide exposure levels. In recent years, studies have suggested that paraoxonases have some role in the prevention of oxidative stress and inflammation, and have implicated these enzymes in the modulation of a wide variety of diseases, including atherosclerosis, diabetes, Parkinson's disease, and inflammatory bowel disease.
