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:0000256|ARBA:ARBA00002322}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 a phenolic donor + H2O2 = 2 a phenolic radical donor + 2

CC Evidence={ECO:0000256|PIRSR:PIRSR600823-3,
CC ECO:0000256|RuleBase:RU362060};
CC Note=Binds 2 calcium ions per subunit. {ECO:0000256|PIRSR:PIRSR600823-
CC 3, ECO:0000256|RuleBase:RU362060};
CC -!- COFACTOR:
CC Name=heme b; Xref=ChEBI:CHEBI:60344;
CC Evidence={ECO:0000256|PIRSR:PIRSR600823-3,
CC ECO:0000256|RuleBase:RU362060};
CC Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per subunit.
CC {ECO:0000256|PIRSR:PIRSR600823-3, ECO:0000256|RuleBase:RU362060};
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000256|RuleBase:RU362060}.
CC -!- SIMILARITY: Belongs to the peroxidase family. Ascorbate peroxidase
CC subfamily. {ECO:0000256|ARBA:ARBA00006873}.
CC -!- SIMILARITY: Belongs to the peroxidase family. Classical plant (class
