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."
