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.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:Preferentially expressed in roots, but also detected in flowers, leaves and stems.DEVELOPMENTAL STAGE:Up-regulated during leaf development.INDUCTION:Late-induced by Al treatment. Expression increased over 48 hours of Al treatment. Induced by oxidative stress. 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.SEQUENCE CAUTION:Sequence=AAG40051.2; Type=Frameshift; Positions=176; "
