Protein

Peroxidase 64

Gene

PER64

Organism
Arabidopsis thaliana (Mouse-ear cress)
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:
  • 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

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
