CC   -!- FUNCTION: Catalyzes the degradation of hydrogen peroxide (H(2)O(2))
CC       generated by peroxisomal oxidases to water and oxygen, thereby
CC       protecting cells from the toxic effects of hydrogen peroxide.
CC       {ECO:0000250|UniProtKB:P04040}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 H2O2 = O2 + 2 H2O; Xref=Rhea:RHEA:20309, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:15379, ChEBI:CHEBI:16240; EC=1.11.1.6;
CC         Evidence={ECO:0000255|PROSITE-ProRule:PRU10013};
CC   -!- COFACTOR:
CC       Name=heme; Xref=ChEBI:CHEBI:30413;
CC         Evidence={ECO:0000250|UniProtKB:P04040};
CC   -!- SUBUNIT: Homotetramer.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol
CC       {ECO:0000250|UniProtKB:P25819}. Peroxisome matrix
CC       {ECO:0000250|UniProtKB:P25819}.
