These functions might be dependent on each isozyme/isoform in each plant tissue.FUNCTION:Suggested to catalyze the deposition of the aromatic residues of suberin on the cell wall and thus play a role in cell- suberization.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.INDUCTION:During wound-healing and by factors which induce suberization.SIMILARITY:Belongs to the peroxidase family. Classical plant (class III) peroxidase subfamily."
