FUNCTION: Occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide.
CATALYTIC ACTIVITY: 2 H₂O₂ = O₂ + 2 H₂O.
COFACTOR: Heme group (By similarity).
SUBCELLULAR LOCATION: Peroxisome (By similarity).
SIMILARITY: Belongs to the catalase family.
