Protein

Peroxidase 53

Gene

PER53

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at protein 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.
Closely linked to lignin formation by showing monolignol substrate specificity.

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:
  • Ca2+Note: Binds 2 calcium ions per subunit.
  • heme bNote: Binds 1 heme b (iron(II)-protoporphyrin IX) group per subunit.
