Addtional InformationFUNCTION:Removal of H(2)O(2), oxidation of toxic reductants, biosynthesis and degradation of lignin, suberization, auxin catabolism, response to environmental stresses such as wounding, pathogen attack and oxidative stress. These functions might be dependent on each isozyme/isoform in each plant tissue.FUNCTION:Exhibits a Ca(2)-pectate binding affinity which could be interpreted in vivo as a specificity to interact with the pectic structure of the cell wall.CATALYTIC ACTIVITY:Donor H(2)O(2) = oxidized donor 2 H(2)O.COFACTOR:Binds 1 heme B (iron-protoporphyrin IX) group per subunit (By similarity).COFACTOR:Binds 2 calcium ions per subunit (By similarity).Note=Carboxy-terminal extension appears to target the protein to vacuoles.TISSUE SPECIFICITY:Expressed in roots and leaves.DEVELOPMENTAL STAGE:Expressed in the first stage of developing seeds.INDUCTION:Induced either by incompatible fungal pathogen attack, or by methyl jasmonate, a plant defense-related signaling molecule.MISCELLANEOUS:There are 73 peroxidase genes in A.thaliana.SIMILARITY:Belongs to the peroxidase family. Classical plant (class III) peroxidase subfamily.
