Protein

Peroxidase 2

Gene

PER2

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

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 activityi

2 phenolic donor + H2O2 = 2 phenoxyl radical of the donor + 2 H2O.

Cofactori

Protein has several cofactor binding sites:
  • heme bPROSITE-ProRule annotationNote: Binds 1 heme b (iron(II)-protoporphyrin IX) group per subunit.PROSITE-ProRule annotation
  • Ca2+PROSITE-ProRule annotationNote: Binds 2 calcium ions per subunit.PROSITE-ProRule annotation
