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:Plays an integral role in secondary cell wall biosynthesis by the polymerization of cinnamyl alcohols into lignin and by forming rigid cross-links between cellulose, pectin, hydroxy-proline-rich glycoproteins, and lignin.CATALYTIC ACTIVITY:Donor H(2)O(2) = oxidized donor 2 H(2)O.COFACTOR:Binds 2 calcium ions per subunit.COFACTOR:Binds 1 heme B (iron-protoporphyrin IX) group per subunit.TISSUE SPECIFICITY:Mesophyll protoplasts and to a much lesser extent, roots and germinating seeds.DEVELOPMENTAL STAGE:Before reinitiation of the DNA replicational activity.SIMILARITY:Belongs to the peroxidase family. Classical plant (class III) peroxidase subfamily.
