Protein: Peroxidase 64 (Atperox P64) (EC 1.11.1.7) (ATP17a) (PRXR4) (Q43872)
Organism: Arabidopsis thaliana (Mouse-ear cress)
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.
Subcellular location: Secreted {ECO:0000255|PROSITE-ProRule:PRU00297}.
