CC   -!- FUNCTION: Removal of H(2)O(2), oxidation of toxic reductants,
CC       biosynthesis and degradation of lignin, suberization, auxin
CC       catabolism, response to environmental stresses such as wounding,
CC       pathogen attack and oxidative stress. These functions might be
CC       dependent on each isozyme/isoform in each plant tissue.
CC   -!- CATALYTIC ACTIVITY: Donor + H(2)O(2) = oxidized donor + 2 H(2)O.
CC   -!- COFACTOR: Binds 1 heme B (iron-protoporphyrin IX) group per
CC       subunit (By similarity).
CC   -!- COFACTOR: Binds 2 calcium ions per subunit (By similarity).
CC   -!- SUBCELLULAR LOCATION: Secreted (By similarity).
CC   -!- SIMILARITY: Belongs to the peroxidase family. Classical plant
CC       (class III) peroxidase subfamily.
