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.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).TISSUE SPECIFICITY:Mainly expressed in roots.INDUCTION:Positively light-regulated during the firt stage of development. Up-regulated transiently by a cold treatment. Induced in shoots of plants subjected to a long Fe deficiency stress.Down-regulated by salicylic acid, 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.
