General annotation (Comments)

Function	Removal of H2O2, 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.
Catalytic activity	Donor + H2O2 = oxidized donor + 2 H2O. UniProtKB P22195
Cofactor	Binds 2 calcium ions per subunit By similarity. UniProtKB P22195 Binds 1 heme B (iron-protoporphyrin IX) group per subunit By similarity. UniProtKB P22195
Subcellular location	Secreted By similarity. UniProtKB P84516
Sequence similarities	Belongs to the peroxidase family. Classical plant (class III) peroxidase subfamily.
