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 Probable. The enzyme activity has to be proved.

Catalytic activity

2 phenolic donor + H2O2 = 2 phenoxyl radical of the donor + 2 H2O.

Cofactor

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

Binds 2 calcium ions per subunit By similarity.

Subcellular location

Secreted By similarity.

Miscellaneous

There are 73 peroxidase genes in A.thaliana.

Sequence similarities

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

Caution

Lacks the distal histidine (here Ser-77), present in the active site, which is one of the conserved features of the classical plant (class III) peroxidase family.

Sequence caution

The sequence AAB64327.1 differs from that shown. Reason: Erroneous initiation.
