catalase
catalase An enzyme, found in peroxisomes, that catalyses the decomposition of hydrogen peroxide, which results from oxidation reactions in the cell (see also superoxide dismutase), into water and oxygen. High concentrations of catalase are found in the liver. Catalase is the fastest known enzyme; it is employed in the rubber industry to form oxygen, which converts latex to foam rubber.
