Protein attributes

Sequence length	721 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity By similarity.
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.
Subunit structure	Homodimer or homotetramer By similarity.
Post-translational modification	The covalent Trp-Tyr-Met adduct is important for the catalase, but not the peroxidase activity of the enzyme By similarity.
Sequence similarities	Belongs to the peroxidase family. Peroxidase/catalase subfamily.
