Une catalase (du grec kataluein, « dissoudre ») est une oxydoréductase héminique qui catalyse la dismutation du peroxyde d'hydrogène en eau et dioxygène : 2 H 2 O 2 → O 2 + 2 H 2 O. Ces enzymes sont formées de quatre chaînes polypeptidiques d’environ 500 résidus d'acides aminés, comportant chacune une molécule d'hème. Catalase catalyzes the disproportionation reaction 2H 2 O 2 → 2H 2 O + O 2, thereby helping to prevent oxidative damage to cells caused by H 2 O 2.
