The inhibition of enzymes by beryllium.
1. The action of beryllium on the following enzymes has been examined: alkaline phosphatase (Escherichia coli and kidney), acid phosphatase, phosphoprotein phosphatase, apyrase (potato), adenosine triphosphatase (liver nuclei, liver mitochondria, brain microsomes), glucose 6-phosphatase, polysaccharide phosphorylases a and b, phosphoglucomutase, hexokinase, phosphoglyceromutase, ribonuclease, A...
متن کاملPhotocatalytic Activity of ZnO Nanoparticles (Bare, Doped and Co-doped with Mg and La) in the Removal of Rhodamine B from Aqueous Solutions by UVC Irradiation
Background & objectives: The organic dyes are environmental pollutants that pour into water sources by industrial wastewater. It is necessary to develop effective methods for removing pollutants. The aim of this study was to evaluate photocatalytic efficiency of bare ZnO nanoparticles doped with Mg and La (1 to 6% by weight) and Mg 5% -La 5% / ZnO and Mg6%-La4% / ZnO nanoparticles in the remova...
متن کاملRate-limiting steps for the esterase and dehydrogenase reaction catalyzed by horse liver aldehyde dehydrogenase.
Horse liver aldehyde dehydrogenase, like other aldehyde dehydrogenases, is capable of hydrolyzing esters such as nitrophenyl acetate. Pre-steady state and burst kinetics were performed using substrate levels of enzyme to determine whether the rate-limiting step occurred prior to or after the formation of an acyl enzyme intermediate. A burst was found by both techniques for the dehydrogenase rea...
متن کاملSpecificity of esterases. IV. Behavior of horse liver esterase towards a homologous series of n-fatty acid esters.
E’nxymes-(1) Purified horse liver esterase, prepared as described previously (2); (2) a crude extract of horse liver acetone powder, obtained by stirring the powder for several hours with a 2.5 per cent sodium acetate solution (3) followed by centrifugation. Substrates-These were esters of n-fatty acids and m-hydroxybenzoic acid, prepared by the same procedures as given previously (4, 1) for th...
متن کاملA Comparative Photocatalytic Activity of ZnO/SiO2 and V2O5-ZnO/SiO2 by Investigating the Degradation of Rhodamine B
ZnO/SiO2 was prepared using sol-gel method, and vanadium particles were loaded on this nano-photocatalyst by wet incipient method. They characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive (EDX) analysis andFouriertransform infrared spectroscopy (FT-IR). The XRD patterns showed that the zinc oxide samples have a wurtzite structure and vanadium dope...
