Product name:Catalase
CAS:9001-05-2
Specification:1g
Description:
Catalase is a common enzyme found in nearly all living organisms that are exposed to oxygen, where it functions to catalyze the decomposition of hydrogen peroxide to water and oxygen. Catalase has one of the highest turnover numbers of all enzymes; one molecule of catalase can convert millions of molecules of hydrogen peroxide to water and oxygen per second.
Catalase is an enzyme that catalyzes the decomposition of hydrogen peroxide molecules. 2H2O2 - →2H2O+O2 system is called H2O2; H2O2 oxidoreductase (E, C, 1, 11, 1, 6), whose auxiliary group is heme and molecular weight is 250,000, exists as a tetramer. Catalase is present in almost all animal cells and is widely present in plants and all microorganisms except true anaerobic bacteria. Animal liver, red blood cell and kidney contain abundant catalase, which is mainly found in cell microsomes (also known as peroxidases).
In mitochondrial respiratory chain, flavin electron transfer of enzyme and other oxidation reaction, the part will or may generate toxic REDOX reaction products, the most main is super oxygen ions O2 - and H2O2, they are very lively in chemical properties and may be irreversible damage to certain biological molecules, super oxide ion in cells under the action of super oxide dismutase (sod) content, into oxygen and hydrogen peroxide. The main function that crosses oxygen to pass hydrogen enzyme, it is to decompose hydrogen peroxide, prevent the accumulation of hydrogen peroxide, make a cell avoid the harm of hydrogen peroxide, hydrogen peroxide of catalysis hydrogen peroxide breaks down rate very quickly, faster than peroxidase 104 times, every molecular enzyme every second can catalyze decompose the hydrogen peroxide of 44,000 molecules.
