Names and origin

Protein names	Recommended name: Peroxidase 2 EC=1.11.1.7
Organism	Hordeum vulgare (Barley)
Taxonomic identifier	4513 [NCBI]
Taxonomic lineage	Eukaryota › Viridiplantae › Streptophyta › Embryophyta › Tracheophyta › Spermatophyta › Magnoliophyta › Liliopsida › Poales › Poaceae › BEP clade › Pooideae › Triticeae › Hordeum

Protein attributes

Sequence length	170 AA.
Sequence status	Fragment.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

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. These functions might be dependent on each isozyme/isoform in each plant tissue. Involved in defense response to powdery meldew fungus.
Catalytic activity	Donor + H₂O₂ = oxidized donor + 2 H₂O.
Cofactor	Binds 2 calcium ions per subunit. Binds 1 heme B (iron-protoporphyrin IX) group per subunit.
Sequence similarities	Belongs to the peroxidase family. Classical plant (class III) peroxidase subfamily.
