Current Protocols in Toxicology, 2006
AbstractCatalase (hydrogen peroxide/hydrogen peroxide oxidoreductase) is an important cellular antioxidant enzyme that defends against oxidative stress. It is found in the peroxisomes of most aerobic cells. It serves to protect the cell from toxic effects of high concentrations of hydrogen peroxide (H2O2) by catalyzing its decomposition into molecular ...

Biochemical Genetics, 1970
An examination of three inbred strains of mice differing with respect to liver and kidney catalase activity reveals two distinct genetic factors controlling the level of liver catalase activity. The first genetic factor controls the catalytic activity of the enzyme.

Abstract The enzyme catalase, widely distributed in animal tissues, consists of four identical subunits. The molecular weight is approximately 240000. The major active component of the enzyme, ferri protoporphyrin (haematin).

Electron Transfer in Catalases and Catalase-Peroxidases
2013Catalases (EC 1.11.1.6) are enzymes that catalyze the disproportionation of hydrogen peroxide into water and molecular oxygen by means of a heme iron or a dimanganese active site. They are crucial metalloproteins regulating the cellular concentration of hydrogen peroxide, which has a concentration-dependent dual role in cell signaling and oxidative ...
