Kinetic dependence of phospholipase A 2 activity on the detergent Triton X-100.
A kinetic analysis is presented for the dependence of one form of phospholipase A(2) from cobra (Naja naja) venom on the presence of the nonionic detergent Triton X-100 for its activity towards egg phosphatidylcholine and synthetic dipalmitoyl glycerophosphorylcholine as substrates. An automatic recording pH-stat apparatus was employed in order to continuously monitor enzyme activity. The resul...
متن کاملTemperature Dependence of Triton X-100 Micelle Size and Hydration?
Quasi-elastic light scattering spectroscopy was used to measure the mutual diffusion coefficient, D,, of Triton X-100 micelles in aqueous solution and the translational diffusion coefficient, D,, of mesoscopic probes in the same solutions. We apply conventional hydrodynamic treatments of diffision under the assumption that Triton X-100 minimal micelles are adequately represented as hard spheres...
متن کاملPhotocatalytic Degradation of Triton X-100 by Zinc oxide Nanoparticles
In this study the application of ZnO nanoparticles to UV photocatalytic degradation of nonionic surfactantTriton X-100 in aqueous media was investigated. The affecting factors on the photodegradation such as TritonX-100 initial concentration, nanocatalyst weight, pH, temperature and other parameters were studied anddescribed in details. The degradation rate was found to be strongly influenced b...
متن کاملEffect of Polyethylene Glycol and Triton X-100 on the Enzymatic Treatment of Bisphenol A
The current study includes the screening of indigenous extracellular laccase producing fungus from the soil, identified as Phanerochaete chrysosporiumspecies.The selected strain was applied under the optimized condition for the production of laccase in the solid state fermentation. The effect of polyethylene glycol and Triton X-100 on the enhancement of enzyme activity and bi...
متن کاملInteractions of rat brain acetylcholinesterase with the detergent Triton X-100 and the organophosphate paraoxon.
Inhibition of the critical enzyme acetylcholinesterase (E.C. 3.1.1.7) with subsequent cholinergic crisis is the mechanism of acute toxicity of the organophosphorus insecticides (B. E. Mileson et al., 1998, Toxicol. Sci.41, 8-20). Consequently, measurement of acetylcholinesterase activity is important for evaluating the mammalian toxicity of this commonly used class of insecticides. While mammal...
