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 (Probable). The enzyme activity has to be proved.
Miscellaneous
There are 73 peroxidase genes in A.thaliana.
Catalytic activity
- 2 a phenolic donor + H2O2 = 2 a phenolic radical donor + 2 H2O
Cofactor
Protein has several cofactor binding sites:
Note: Binds 1 heme b (iron(II)-protoporphyrin IX) group per subunit.
Note: Binds 2 calcium ions per subunit.
