Background: Light and photosensitizers affectthe survival of bacteria in natural environments. Also light and photosensitizers are used for disinfection of materials such as blood, blood products, and water. Objectives: The present study was aimed toinvestigate the effect of different wavelengths of visible light and UV-A on the synthesis of some oxidative stress enzymes of Escherichia coli (E....

Studies of our experiment are related to the binding of enzymes to antibodies. This involves the formation of a stable, covalent linkage between an enzyme & antibody. We used different Enzymes for this studies which are altered in binding action. Enzymes we used-e.g. Horseradish peroxidase (HRPO), urease, or alkaline phosphatase. Studies of Enzyme and an antigen-specific monoclonal or polyclona...

Functionalized gold nanoparticles bind selectively to cytochrome c or cytochrome c peroxidase and inhibit enzyme turnover.

Peroxidase enzyme plays an important role in pharmaceutical, Industrial and various research laboratories. This enzyme can be purified by various different method. Our research trend was to purify the enzyme in a convenient and easy way. For this purpose a new affinity column was prepare by immobilizing PABA to N-HydroxySuccinamaideagarose gel. The presence of peroxidase was investigated on var...

2-Cys Prxs are H2O2-specific antioxidants that become inactivated by enzyme hyperoxidation at elevated H2O2 levels. Although hyperoxidation restricts the antioxidant physiological role of these enzymes, it also allows the enzyme to become an efficient chaperone holdase. The critical molecular event allowing the peroxidase to chaperone switch is thought to be the enzyme assembly into high molecu...

A diverse collection of actinomycete strains were screened for production of extracellular peroxidase activity by adapting a chemiluminescence analysis system developed for horseradish peroxidase-based enzyme-linked immunosorbent assay. Extracellular peroxidase activity was found to be common but quantitatively variable, and this rapid and sensitive screening system permitted identification of ...

Nowadays the treatment of environmental pollutants such as synthetic dyes (used in multiple industries paper, textile, food, plastic and pharmaceutical) has received much attention, especially for biotechnological treatments using both native artificial enzymes. In this context, many enzymes have been reported to efficiently perform dye degradation. Peroxidase is one enzyme, which causes degrad...
