dc.description.abstract | Thermococcus onnurineus NA1 is known to grow by the anaerobic oxidation of formate to CO2 and H-2, a reaction that operates near thermodynamic equilibrium. Here we demonstrate that this reaction is coupled to ATP synthesis by a transmembrane ion current. Formate oxidation leads to H+ translocation across the cytoplasmic membrane that then drives Na+ translocation. The ion-translocating electron transfer system is rather simple, consisting of only a formate dehydrogenase module, a membrane-bound hydrogenase module, and a multisubunit Na+/H+ antiporter module. The electrochemical Na+ gradient established then drives ATP synthesis. These data give a mechanistic explanation for chemiosmotic energy conservation coupled to formate oxidation to CO2 and H-2. Because it is discussed that the membrane-bound hydrogenase with the Na+/H+ antiporter module are ancestors of complex I of mitochondrial and bacterial electron transport these data also shed light on the evolution of ion transport in complex I-like electron transport chains. | - |
