CC   -!- FUNCTION: Removal of H(2)O(2), oxidation of toxic reductants,
CC       biosynthesis and degradation of lignin, suberization, auxin catabolism,
CC       response to environmental stresses such as wounding, pathogen attack
CC       and oxidative stress. These functions might be dependent on each
CC       isozyme/isoform in each plant tissue. {ECO:0000305}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 a phenolic donor + H2O2 = 2 a phenolic radical donor + 2
CC         H2O; Xref=Rhea:RHEA:56136, ChEBI:CHEBI:15377, ChEBI:CHEBI:16240,
CC         ChEBI:CHEBI:139520, ChEBI:CHEBI:139521; EC=1.11.1.7;
CC   -!- COFACTOR:
CC       Name=heme b; Xref=ChEBI:CHEBI:60344;
CC         Evidence={ECO:0000250|UniProtKB:P22195,
CC         ECO:0000255|PROSITE-ProRule:PRU00297};
CC       Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per subunit.

CC         ECO:0000255|PROSITE-ProRule:PRU00297};
CC       Note=Binds 2 calcium ions per subunit. {ECO:0000250|UniProtKB:P22195,
CC       ECO:0000255|PROSITE-ProRule:PRU00297};
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P84516,
CC       ECO:0000255|PROSITE-ProRule:PRU00297}.
CC   -!- SIMILARITY: Belongs to the peroxidase family. Classical plant (class
CC       III) peroxidase subfamily. {ECO:0000255|PROSITE-ProRule:PRU00297}.
