General annotation (Comments)

Function

Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity By similarity. HAMAP MF_01961

Catalytic activity

Donor + H2O2 = oxidized donor + 2 H2O. HAMAP MF_01961

2 H2O2 = O2 + 2 H2O. HAMAP MF_01961

Cofactor

Binds 1 heme B (iron-protoporphyrin IX) group per dimer By similarity.

Subunit structure

Homodimer or homotetramer By similarity. HAMAP MF_01961

Post-translational modification

The covalent Trp-Tyr-Met adduct is important for the catalase, but not the peroxidase activity of the enzyme By similarity. HAMAP MF_01961

Sequence similarities

Belongs to the peroxidase family. Peroxidase/catalase subfamily.
