CC -!- FUNCTION: Bifunctional enzyme with both catalase and broad-spectrum CC peroxidase activity. {ECO:0000256|HAMAP-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:0000256|ARBA:ARBA00001378, ECO:0000256|HAMAP- CC Rule:MF_01961, ECO:0000256|RuleBase:RU003451}; 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:0000256|HAMAP- CC Rule:MF_01961, ECO:0000256|RuleBase:RU003451}; CC -!- COFACTOR: CC Name=heme b; Xref=ChEBI:CHEBI:60344; CC Evidence={ECO:0000256|HAMAP-Rule:MF_01961}; CC Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per dimer. CC {ECO:0000256|HAMAP-Rule:MF_01961}; CC -!- SUBUNIT: Homodimer or homotetramer. {ECO:0000256|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:0000256|HAMAP-Rule:MF_01961}. CC -!- SIMILARITY: Belongs to the peroxidase family. Peroxidase/catalase CC subfamily. {ECO:0000256|HAMAP-Rule:MF_01961, CC ECO:0000256|RuleBase:RU003451}. CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01961}.
