Purity ~90% (SDS-PAGE). Hydrolyzes the toxic metabolites of a variety of organophosphorus insecticides. Capable of hydrolyzing a broad spectrum of organophosphate substrates and lactones, and a number of aromatic carboxylic acid esters. Mediates an enzymatic protection of low density lipoproteins against oxidative modification and the consequent series of events leading to atheroma formation. Source: Recombinant protein corresponding to aa2-355 from human PON1, fused to GST-Tag at N-terminal, expressed in E. coli. Molecular Weight: ~66.6kD AA
