TPX, also known as lipid hydroperoxide peroxidase, is a member of the peroxiredoxin family of antioxidant enzymes, which reduce hydrogen peroxide and alkyl hydroperoxides. This protein may play an important role in thioredoxin peroxidase activity. Source: Recombinant corresponding to aa1-168 from human TPX, fused to His-tag at N-terminus expressed in E.coli.
