CC   -!- FUNCTION: Bifunctional enzyme with both catalase and broad-spectrum
CC       peroxidase activity. {ECO:0000255|HAMAP-Rule:MF_03108}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=AH2 + H2O2 = A + 2 H2O; Xref=Rhea:RHEA:30275,
CC         ChEBI:CHEBI:13193, ChEBI:CHEBI:15377, ChEBI:CHEBI:16240,
CC         ChEBI:CHEBI:17499; EC=1.11.1.21; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_03108};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 H2O2 = 2 H2O + O2; Xref=Rhea:RHEA:20309, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:15379, ChEBI:CHEBI:16240; EC=1.11.1.21;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_03108};
CC   -!- COFACTOR:
CC       Name=heme b; Xref=ChEBI:CHEBI:60344;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_03108};
CC       Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per monomer.
CC       {ECO:0000255|HAMAP-Rule:MF_03108};
CC   -!- SUBUNIT: Homodimer or homotetramer. {ECO:0000255|HAMAP-Rule:MF_03108}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03108}.
CC   -!- PTM: Formation of the three residue Trp-Tyr-Met cross-link is important
CC       for the catalase, but not the peroxidase activity of the enzyme.
CC       {ECO:0000255|HAMAP-Rule:MF_03108}.
CC   -!- SIMILARITY: Belongs to the peroxidase family. Peroxidase/catalase
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_03108}.
