enzymes catalyze many biological reactions. the rates of chemical reaction in the presence ofenzymes are, in some cases, accelerated more than 10 orders of magnitude relative to thecorresponding rates in solution.in this paper a comparison between optimized structures of two enzyme molecules in aspect ofenergy and dipole moment in different conditions including presence of metallic ion, without...

background: it has been shown that zinc has an effect on physiological responses in animals and birds. on the other hand, dietary phytase in poultry results in increased availability of zinc. objectives: this study was conducted to investigate the effects of zinc oxide (zno) and escherichia coli-derived 6-phytase supplemented diets on the plasma metabolites and enzyme activities of broiler bree...

the aim of this study was to find the optimal conditions of a newly isolated streptomyces strain jrs 19. screening for keratinase producing bacteria and their keratinase production were investigated. the keratinase produced by the isolate was purified by chromatographic techniques and the optimum ph maintained was 7.0 and maintained at different temperatures viz., 20ºc, 25ºc, 30ºc, 35ºc and 40º...

background and objectives: ensiling is a conservation method for forage crops. it is based on the fact that anaerobe lactic acid bacteria (lab) convert water-soluble carbohydrates into organic acids. therefore, ph decreases and the forage is preserved. the aim of this study was to isolate special kinds of lactic acid bacteria from silage and to study the effect of bacteria, inulin and enzymes a...

voriconazole is an antifungal triazole, approved for management of invasive fungal diseases in patients. it is absorbed during two hours and its serum levels will be above 90%, based on the underlying factors, when the drug is administered orally. voriconazole shows a propotional increase in an area under the plasma concentration-time curve (auc), with increasing dose. plasma protein binding of...

Despite the availability of various alkaline phosphatase (ALP) isoenzymes, the calf enzyme is being used in current enzyme assays as the detector enzyme. The glycosylation pattern of this enzyme makes it a suitable ligand for binding to wheat germ agglutinin lectin (WGA). As a result of this property, the enzyme can not be used as a conjugate with this lectin, and the calf enzyme conjugates can...
