Q96511 · PER69_ARATH

Function

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.

Miscellaneous

There are 73 peroxidase genes in A.thaliana.

Catalytic activity

Cofactor

Protein has several cofactor binding sites:
heme b (UniProtKB | Rhea| CHEBI:60344 )

Note: Binds 1 heme b (iron(II)-protoporphyrin IX) group per subunit.
Ca2+ (UniProtKB | Rhea| CHEBI:29108 )

Note: Binds 2 calcium ions per subunit.
