Description
Description
Peroxiredoxins are a family of thiol-dependent antioxidant proteins that catalyze the reduction of hydrogen peroxide, peroxynitrite and a wide range of organic hydroperoxides (ROOH) to the corresponding alcohol (ROH) and water. These proteins function as peroxidases only when coupled to a sulfhydryl-reducing system such as thioredoxin or glutathione. Catalytic activity is dependent on the oxidation of a conserved cysteine residue at the active site. (Adapted from FBrf0139661, PMID:12517450.)
Notes on Group

Prx5 is an atypical 2-Cys peroxiredoxin (FBrf0231274).

DJ-1α and dj-1β are predicted to encode atypical peroxiredoxin-like peroxidases, based on homology to mouse DJ-1 (Park7).

Gtpx and Gpxl encode the only two members of the glutathione peroxidase family in D. melanogaster, but they exhibit thioredoxin-dependent peroxiredoxin activity rather than glutathione peroxidase activity (FBrf0158751).
