Protein
Alkyl hydroperoxide reductase E
Organism
Mycobacterium tuberculosis (strain CDC 1551 / Oshkosh)
Function
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 represent an important antioxidant defense against cytotoxic peroxides, especially peroxynitrite, which can be formed by activated macrophages during infection.
Similarity
Belongs to the peroxiredoxin family. AhpE subfamily.
