| Addtional Information | FUNCTION: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.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; |
