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."
