Q9FLV5 · PER61_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 (Probable). The enzyme activity has to be proved.

Miscellaneous

There are 73 peroxidase genes in A.thaliana.

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.

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.
