Enzyme Information
| 1.11.1.6 | Catalase. based on mapping to UniProt P21179 2 H(2)O(2) = O(2) + 2 H(2)O. -!- 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. |
