Catalase peroxidase.
based on mapping to UniProt P13029
(1) Donor + H(2)O(2) = oxidized donor + 2 H(2)O. (2) 2 H(2)O(2) = O(2) + 2 H(2)O.
-!- Differs from EC 1.11.1.7, peroxidase, in having a relatively high catalase (EC 1.11.1.6) activity with H(2)O(2) as donor, releasing O(2); both activities use the same heme active site. -!- In Mycobacterium tuberculosis it is responsible for activation of the commonly used antitubercular drug, isoniazid.
