IUBMB Comments
A hemoprotein. A manganese protein containing MnIII 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, catalase-peroxidase.
