General annotation (Comments)

Function	Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity By similarity. HAMAP MF_01961
Catalytic activity	2 H2O2 = O2 + 2 H2O. HAMAP MF_01961 Donor + H2O2 = oxidized donor + 2 H2O. HAMAP MF_01961
Cofactor	Binds 1 heme B (iron-protoporphyrin IX) group per dimer By similarity. HAMAP MF_01961
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.
