CC -!- FUNCTION: Bifunctional enzyme with both catalase and broad-spectrum
CC peroxidase activity. {ECO:0000255|HAMAP-Rule:MF_01961}.
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_01961};
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_01961};
CC -!- COFACTOR:
CC Name=heme b; Xref=ChEBI:CHEBI:60344;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01961};
CC Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per dimer.
CC {ECO:0000255|HAMAP-Rule:MF_01961};
CC -!- SUBUNIT: Homodimer or homotetramer. {ECO:0000255|HAMAP-Rule:MF_01961}.
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_01961}.
CC -!- SIMILARITY: Belongs to the peroxidase family. Peroxidase/catalase
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_01961}.
