ENZYME entry: EC 1.11.1.6

Accepted Name
Catalase.
Reaction catalysed
2 H(2)O(2) <=> O(2) + 2 H(2)O
Cofactor(s)
Heme; Mn(2+).
Comment(s)
  • A manganese protein containing Mn(III) in the resting state, which also belongs here, is often called pseudocatalase.
  • The enzymes from some organisms, such as Penicillium simplicissimum, can also act as a peroxidase (EC 1.11.1.7) for which several organic substances, especially ethanol, can act as a hydrogen donor.
  • Enzymes that exhibit both catalase and peroxidase activity belong under EC 1.11.1.21.
