These functions might be dependent on each isozyme/isoform in each plant tissue.FUNCTION:May be implicated in the systemic acquired resistance response via the salicylic acid signal transduction pathway.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.INDUCTION:Transiently induced by ozone treatment. Up-regulated during a continuous drought stress. Early induced by benzothiadiazol, a chemical analog of salicylic acid. Enhanced expression following both compatible or incompatible pathogen attacks.MISCELLANEOUS:There are 73 peroxidase genes in A.thaliana.SIMILARITY:Belongs to the peroxidase family. Classical plant (class III) peroxidase subfamily."
