Protein attributes

Sequence length	335 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

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. Closely linked to lignin formation by showing monolignol substrate specificity.
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.
Tissue specificity	Mainly expressed in roots.
Miscellaneous	There are 73 peroxidase genes in A.thaliana.
Sequence similarities	Belongs to the peroxidase family. Classical plant (class III) peroxidase subfamily.
