Protein attributes

Sequence length	314 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology.

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.
Cofactor	Binds 2 calcium ions per subunit. Binds 1 heme B (iron-protoporphyrin IX) group per subunit.
Subcellular location	Secreted By similarity.
Sequence similarities	Belongs to the peroxidase family. Classical plant (class III) peroxidase subfamily.
