CATALASE - AN OVERVIEW | SCIENCEDIRECT TOPICS
Web Catalase (CAT) is a heme-containing enzyme that is one of the most potent catalysts known (Salin, 1988); it is found abundantly in a cellular compartment called the peroxisome. CAT catalyzes reactions that are crucial to life—for example, the conversion of H2 O 2, a powerful and potentially harmful oxidizing agent, to water and molecular oxygen.

Web Oct 1, 2018 Catalase is a tetramer of four polypeptide chains, each over 500 amino acids long. It contains four porphyrin heme (iron) groups that allow the enzyme to react with the hydrogen peroxide. Catalase has a fairly broad range of working from 4 to 11 optimum pH (Beers, 1961, Calera et al., 2000, Correia et al., 1994, Diaz et al., 2012).
