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: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).ALTERNATIVE PRODUCTS:Event=Alternative splicing; Named isoforms=1; Comment=A number of isoforms are produced. According to EST sequences; Name=1; IsoId=Q9SLH7-1; Sequence=Displayed;INDUCTION:Late induced by benzothiadiazol, a chemical analog of salicylic acid. Enhanced expression following incompatible bacterial pathogen attack.MISCELLANEOUS:There are 73 peroxidase genes in A.thaliana.SIMILARITY:Belongs to the peroxidase family. Classical plant (class III) peroxidase subfamily.
