Protein

Peroxidase C1A

Gene

PRXC1A

Organism
Armoracia rusticana (Horseradish) (Armoracia laphatifolia)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-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.

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.
