Description

Biochem/physiol Actions

Peroxiredoxins are a novel defined family of peroxidases of approximately 25 kDa that reduce H2O2 and alkyl hydroperoxides and use mainly the thioredoxin (Trx) system (Trx, thioredoxin reductase and NADPH) as electron donor. The peroxiredoxin family includes more than 30 proteins from organisms of all kingdoms. Peroxiredoxin I belongs to the Type I Peroxiredoxin family. This family consists of human natural killer cell enhancing factor (NKEFA), human proliferation associated gene (PAG), mouse macrophage stress induced protein (MSP23), mouse osteoblast specific factor (OSF-3), and rat heme-binding protein (HBP23). These proteins share about 95% homology.

Peroxiredoxin 1 has a role in cellular peroxide scavenging and it modulates various signaling pathways. It is over-expressed in many cancer cells. It regulates cell growth and signaling by interacting with proteins like c-jun-N-terminal kinase and c-myc.

Packaging

250 μg in glass bottle

Specificity

This product has been shown to catalyze NADPH oxidation in the thioredoxin-thioredoxin reductase system.

Physical form

Lyophilized powder containing HEPES buffer salts and trehalose as stabilizer.

Application

Peroxiredoxin 1 has been used as a standard in enzyme assay for Clostridium difficile recombinant spore coat protein, cotE (with peroxiredoxin and chitinase activity).

General description

Peroxiredoxin 1, an active enzyme, has two cysteine residues which correspond to Cys 47 and Cys 170 of yeast TPx (thioredoxin peroxidase).
