General annotation (Comments)

Function

Removal of H(2)O(2), 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 + H(2)O(2) = oxidized donor + 2 H(2)O.

Cofactor

Binds 1 heme B (iron-protoporphyrin IX) group per subunit By similarity.

Binds 2 calcium ions per subunit By similarity.

Subcellular location

SecretedBy similarity.

Miscellaneous

There are 73 peroxidase genes in A.thaliana.

Sequence similarities

Belongs to the peroxidase family. Classical plant (class III) peroxidase subfamily.

Sequence caution

The sequence CAB39666.1 differs from that shown. Reason: Erroneous gene model prediction.

The sequence CAB79456.1 differs from that shown. Reason: Erroneous gene model prediction.
