Preparation and Storage

Background: Peroxiredoxin 5

Peroxiredoxin-5 (Prx-5 or PRDX5; also AOEB166 and thioredoxin reductase) is a 22 kDa, widely expressed mitochondrial antioxidant enzyme that belongs to the atypical 2-Cys class of the TSA/ahpC family of peroxiredoxins. The precursor molecule is 214 amino acids (aa) in length.  It contains an N-terminal 52 aa mitochondrial targeting (signal) sequence and a 162 aa (17 kDa) mature enzyme that shows a nuclear export signal between aa 58‑67, and a peroxisome targeting motif at aa 212‑214. There are two catalytic cysteines, one at Cys100 and a second at Cys204 of the precursor. Prx-5 is a monomer that is found in mitochondria, cytosol, nucleus and peroxisomes. It is known to reduce H₂O₂ and alkyl hydroperoxides. Prx5 can undergo cleavage after Ala52, generating two splice forms. One shows a deletion of aa 59‑147, while a second shows a deletion of aa 103‑146. Mature human Prx-5 is 78% aa identical to mouse Prx-5, with most differences noted over the first 52 amino acids.
