The inhibition of enzymes by beryllium.
نویسندگان
چکیده
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-esterase (rabbit serum), cholinesterase (horse serum), chymotrypsin. Alkaline phosphatase and phosphoglucomutase are inhibited by 1mum-beryllium sulphate whereas the other enzymes are largely unaffected by 1mm-beryllium sulphate. 2. Possible mechanisms for the inhibition of phosphoglucomutase and alkaline phosphatase are discussed.

The effect of beryllium on certain enzymes.
Within recent years a number of reports have appeared demonstrating the toxicity of beryllium in humans and animals. Relatively little is known, however, about the mode of action of beryllium in the body. Klemperer, Miller, and Hill (l), as well as Crier, Hood, and Hoagland (2), have demonstrated an inhibitory action of beryllium on alkaline phosphatase and have suggested the possibility that t...
متن کاملThe inhibition of phosphoglucomutase by beryllium.
1. The inhibition of phosphoglucomutase by beryllium has been examined. 2. Inhibition by beryllium does not occur unless a complex-forming agent such as cysteine or imidazole is present. It is therefore similar to activation by magnesium. 3. The inhibition is progressive and the rate follows first-order kinetics, which may be defined by a bimolecular rate constant. 4. In the presence of magnesi...
متن کاملInteraction Study of 1, 3 Substituted Isatin Derivatives with Anti Inflammatory Properties with Cyclooxygenase 1 and 2 Enzymes by Molecular Docking Method
Introduction: Inflammation as the body's defense response is accompanied with various diseases. Prostaglandins are major mediators of inflammation produced by the cyclooxygenase enzymes. So inhibitors of these enzymes can be effective in treating inflammation. There are reports of inhibition of these enzymes by isatin derivatives to control inflammation. Isatin is a heterocyclic compound whose...
متن کاملDesign and Synthesis of New Benzimidazole and Pyrimidine Derivatives as α-glucosidase Inhibitor
In an endeavor to find a novel series of antihyperglycemic agents, new benzimidazole and pyrimidine derivatives were successfully synthesized efficiently in high yield with high purity, starting from amino acids in the presence of phosphorus oxychloride (POCl3). The synthesized compounds were identified by 1H-NMR, 13C-NMR, FT-IR spectroscopic techniques and elemental analysis. All products were...
متن کاملInvestigating the Bio-corrosion Inhibition Effect of Enzymes in Circulating Cooling Water System
To avoid the secondary pollution that inorganic corrosion inhibitor may cause in circulating cooling water, the bio-corrosion inhibition effect of lysozyme, catalase, lipase, and laccase, as the biologic inhibitors without the above problem, and the increased bio-corrosion inhibition effect of Ca+2 and Mg+2 are studied. An enzyme with corrosion properties was selected by rotary coupon test. The...
