Catalase-peroxidase (EC 1.11.1.21, katG (gene)) is an enzyme with systematic name donor:hydrogen-peroxide oxidoreductase. This enzyme catalyses the following chemical reaction

  1. donor + H2O2 oxidized donor + 2 H2O (peroxidase)
  2. 2 H2O2 O2 + 2 H2O (catalase)

This enzyme is a strong catalase with H2O2 as donor which releases O2.
