Q69RI4 · Q69RI4_ORYSJ

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.

Catalytic activity

Cofactor

Protein has several cofactor binding sites:
Ca2+ (UniProtKB | Rhea| CHEBI:29108 )

Note: Binds 2 calcium ions per subunit.
heme b (UniProtKB | Rhea| CHEBI:60344 )

Note: Binds 1 heme b (iron(II)-protoporphyrin IX) group per subunit.
