过氧化物酶体的标志酶是过氧化氢酶，它的作用主要是将过氧化氢（H2O2，Hydrogen Peroxide）水解。 氧化酶与过氧化氢酶都存在于过氧化物酶体中，从而对细胞起保护作用。

Peroxidases typically catalyze a reaction of the form: For many of these enzymes the optimal substrate is hydrogen peroxide, but others are more active with organic hydroperoxides such …

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 …

Peroxidases are a group of enzymes that catalyze the oxidation of a substrate by hydrogen peroxide or an organic peroxide. Most peroxidases are ferric heme proteins – one notable …

Peroxidases represent a family of isoenzymes actively involved in oxidizing reactive oxygen species, innate immunity, hormone biosynthesis and pathogenesis of several diseases. …

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 …

Peroxidases are classified as oxidoreductases and are the second largest class of enzymes applied in biotechnological processes. These enzymes are used to catalyze various oxidative …

Peroxidase enzymes contain an active site that binds to hydrogen peroxide and then reacts with specific functional groups in the polymer chains. This reaction leads to the formation of highly …

The heme in the active center of peroxidases reacts with hydrogen peroxide to form highly reactive intermediates, which then oxidize simple substances called peroxidase substrates.

2007年4月13日 · Here, we will discuss the molecular mechanisms by which hydrogen peroxide is sensed and the increasing evidence that antioxidant enzymes play multiple, key roles as …
