Dramatic differences in organophosphorus hydrolase activity between human and chimeric recombinant mammalian paraoxonase-1 enzymes.
Human serum paraoxonase-1 (HuPON1) has the capacity to hydrolyze aryl esters, lactones, oxidized phospholipids, and organophosphorus (OP) compounds. HuPON1 and bacterially expressed chimeric recombinant PON1s (G2E6 and G3C9) differ by multiple amino acids, none of which are in the putative enzyme active site. To address the importance of these amino acid differences, the abilities of HuPON1, G2...

متن کاملEvaluation of the organophosphorus hydrolase enzyme activity in creams and investigation of its stability
The main purpose of this project is investigation of the organophosphorus hydrolase (OPH) enzyme activity in water in oil (w/o) and oil in water (o/w) creams and investigation of the OPH enzyme stability in formulated creams. OPH enzyme was extracted and purified from strain flavobacterium. The w/o and o/w creams were prepared using different formulations. In order to achieve an emulsion with m...
متن کاملEffects of static and electromagnetic fields on human serum paraoxonase-1 activity in vitro
Introduction: In recent years the relationship between electromagnetic fields and coronary artery disease is attracted a considerable attention. Low density lipoprotein (LDL) oxidation is the initial step in the development of atherosclerosis. Paraoxonase1 (PON1) protects LDL and High density lipoprotein (HDL) against oxidative processes, thus preventing the formation of atherogenic (oxidized-L...
متن کاملparaoxonase 1 phenotype and paraoxonase activity in asthmatic patients.
oxidative stress is involved in the pathogenesis of asthma. paraoxonase 1 (pon1) and arylesterase are esterase enzymes displaying antioxidant characteristics. pon1 activity varies widely among individuals and ethnic groups, partly related to polymorphisms. the aim of this study was to determine the activities of pon1 and arylesterase including the phenotype distribution of pon1 in asthmatic pat...
