– Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides. May be an antioxidant enzyme particularly in the developing shoot and photosynthesizing leaf. 2-Cys Prx A Protein, Arabidopsis thaliana, Recombinant (His) is expressed in yeast with N-6xHis tag. The predicted molecular weight is 24.4 kDa and the accession number is Q96291.
