HC1 strain possesses aerobic genes but functions only for oxygen detoxification

1 Oct 28 · 11d ago · 1 article · 1 source · development 1 of 3

Strain HC1 carries genes like cytochrome c oxidase (Cox) associated with aerobic lifestyles, but comparative genomics shows these archaea likely do not respire oxygen. Cox appears to support oxygen detoxification rather than respiration, allowing growth in the presence of aerobes under microoxic conditions.
