Assessment of the carbon monoxide metabolism of the hyperthermophilic sulfate-reducing archaeon Archaeoglobus fulgidus VC-16 by comparative transcriptome analyses


ABSTRACT: The metabolic versatile hyperthermophilic dissimilatory sulfate-reducing archaeon, Archaeoglobus fulgidus VC-16, both utilize carbon monoxide as energy source and is highly resistant to toxic effects of CO. This metabolic capacity was investigated by transcriptional response to growth with CO of cultures supplemented with sulfate (S-CO) or thiosulfate (T-CO), and without external electron acceptor (CO-without election acceptor ).

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):menaq  ...[more]
