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.
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:0000255|PROSITE-ProRule:PRU00297};
CC Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per subunit.
CC {ECO:0000255|PROSITE-ProRule:PRU00297};
CC -!- COFACTOR:
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU00297};
CC Note=Binds 2 calcium ions per subunit. {ECO:0000255|PROSITE-
CC ProRule:PRU00297};
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000255|PROSITE-ProRule:PRU00297}.
CC -!- TISSUE SPECIFICITY: Expressed in the whole plant, with the highest
CC expression in roots.
CC -!- INDUCTION: Up-regulated transiently by a cold treatment.
CC {ECO:0000269|PubMed:12172015}.
CC -!- MISCELLANEOUS: There are 73 peroxidase genes in A.thaliana.
CC -!- SIMILARITY: Belongs to the peroxidase family. Classical plant (class
CC III) peroxidase subfamily. {ECO:0000255|PROSITE-ProRule:PRU00297}.
