The hyperthermophilic, sulfate-reducing archaeon, Archaeoglobus fulgidus, utilizes CO as an energy source and it is resistant to the toxic effects of high CO concentrations.
Herein, transcription profiles were obtained from A.
fulgidus during growth with CO and sulfate or thiosulfate, or without an electron acceptor.
This provided a basis for a model of the CO metabolism of A.
fulgidus.
The model suggests proton translocation by “Mitchell-type” loops facilitated by Fqo catalyzing a Fd red :menaquinone oxidoreductase reaction, as the major mode of energy conservation, rather than formate or H2 cycling during respiratory growth.
The bifunctional CODH (cdhAB-2) is predicted to play an ubiquitous role in the metabolism of CO, and a novel nitrate reductase-associated respiratory complex was induced specifically in the presence of sulfate.
A potential role of this complex in relation to Fd red and APS reduction is discussed.
Multiple membrane-bound heterodisulfide reductase (DsrMK) could promote both energy-conserving and non-energy-conserving menaquinol oxidation.
Finally, the FqoF subunit may catalyze a Fd red :F420 oxidoreductase reaction.
In the absence of electron acceptor, downregulation of F420H2 dependent steps of the acetyl-CoA pathway is linked to transient formate generation.
Overall, carboxidotrophic growth seems as an intrinsic capacity of A.
fulgidus with little need for novel resistance or respiratory complexes.
