Peroxidases are enzymes that primarily function to oxidize hydrogen donors using peroxides. They have a high specificity for hydrogen peroxide and can accept a wide range of hydrogen donors, including polyphenols. These enzymes are glycoproteins with a hematin compound as a cofactor and have molecular weights ranging from 30 to 55 kDa.

2021年5月1日 · Peroxidase is an enzyme in the group of oxidoreductases that is widely distributed in nature. It can catalyze the oxidation of various organic and inorganic substrates by reacting with hydrogen peroxide and similar molecules.

Peroxidases represent a family of isoenzymes actively involved in oxidizing reactive oxygen species, innate immunity, hormone biosynthesis and pathogenesis of several diseases. Different types of peroxidases have organ, tissues, cellular and …

2011年1月13日 · Peroxidases are enzymes that use H2 O 2 as an electron acceptor (EC 1.11.1). In soils, fungi produce manganese peroxidase (EC 1.11.1.13), lignin peroxidase (EC 1.11.1.14) and other broad spectrum peroxidases (EC 1.11.1.7) that are known for their role in depolymerizing lignin.

Many organisms are capable of enzymatically destroying the hydrogen peroxide before it can do much damage. Hydrogen peroxide can be converted to oxygen and water, as follows: 2 H2O2 –> 2 H2O + O2(gas) Although this reaction occurs spontaneously, enzymes increase the …

In this experiment we will evaluate the effects on hydrogen peroxidase of three environmental factors, temperature, pH, and enzyme concentration level. Cow liver was homogenized to provide the supply of hydrogen peroxidase.

Peroxidase enzymes have versatile applications in bioenergy, bioremediation, dye decolorization, humic acid degradation, paper and pulp, and textile industries.

2021年7月23日 · Catalase and peroxidase are heme enzymes that catalyze reactions of hydrogen peroxide. 94,95 In catalase, the enzymatic reaction is the disproportionation of hydrogen peroxide (Reaction 5.82) and the function of the enzyme appears to be prevention of any buildup of that potentially dangerous oxidant (see the discussion of dioxygen toxicity in ...

peroxidase reaction is an important source of oxygen for routine use in some metabolic pathways. Like the oxygen-carrying protein hemoglobin, peroxidase has a heme group at its active site; an iron atom in the heme is essential for the enzyme to function. The reaction rate for an enzyme reaction is the speed at which an enzyme converts
