alkaline protease enzyme produced from bacillus licheniformis ptcc1331 in optimum condition(temperature 37 ?c, 150 rpm, ph=10), is immobilized in different concentrations of sodium alginate using entrapment method, to increase its thermal resistance in detergents, and its activity is measured thereafter. maximum enzymatic activity of 46 was obtained in 2%w/v sodium alginate solution. investigat...

the structural requirements for the inhibitor activity of various furan carboxanilide derivatives against succinate dehydrogenase complex (sdc) activity in mitochondria of either wild or mutant strains of ustilago maydis were investigated with the aid of hansch qsar analysis. it has been found that the inhibitor activity against both types of enzymes is best related to the ??? or ??m of the sub...

This book describes the fibrinolytic enzymes of microbial origin that are able to dissolve endogenous thrombi in vivo. The fibrinolytic enzyme streptokinase for example, is produced by b-hemolytic streptococci and exerts its enzyme action indirectly by activating plasminogen. On the other hand, staphylokinase is produced by Staphylococcus aureus by stoichiometric complexation with plasmin(ogen)...

Objective: Exercise and herbs can possess synergistic effects to control diabetes side-effects. The purpose of the present study was to investigate the effects of high intensity interval training (HIIT) and curcumin supplement on activity levels of superoxide dismutase (SOD) and catalase of heart tissue in diabetic rats. Materials and Methods: Thirty-two male Wistar rats were randomly divi...

In this experiment, wheat plants were exposed to drought stress during seed development then we worked on the obtained seeds. The seed mitochondrial ultra-structure, and antioxidant enzymes in seedling were investigated after exposure to seed accelerated ageing. Drought stress during seed development induced some changes in mitochondrial ultra-structure. Encountering seed development to drought...

Although the structure of an enzyme is often depicted as static, it is dynamic. Hence, a population of chemically identical enzymes has not one, but a distribution of structures at any moment in time. Does this have an effect on the activity of the enzyme? This article reviews experiments designed to test the hypothesis that this distribution of structures results in a distribution of enzyme ac...
