Abstract
- Ferriperoxin is a novel peroxidase essential for aerobiosis of Hydrogenobacter thermophilus. Although the ferriperoxin-deficient mutant (Δfpx) was unable to grow aerobically, a suppressor mutant capable of aerobic growth was obtained after long aerobic cultivation. The alkyl hydroperoxide reductase gene was significantly upregulated in the suppressor mutant, indicating that the enzyme counteracts oxidative stress in the absence of ferriperoxin.
