Catalase (EC # is among the best understood enzymes as well as being ubiquitously present throughout nature. As such, it has been used in schools the world over as an introduction to enzymology. Catalase converts hydrogen peroxide, H2O2, into water, H2O, and oxygen, O2. 78 forms of catalase have been isolated to date from several organisms, including humans, flies, corn, and potatoes. Catalase is related to the Peroxidases, but is distinct in its production of O2.
