Abstract
Experiments with resting cells of Acetobacterium woodii were performed to elucidate the coupling ion used by the ATP synthase. A. woodii synthesized ATP in response to an artificial ΔpH, indicating the presence of a proton‐translocating ATPase. On the other hand, a ΔpNa, as well as a proton diffusion potential, could serve as a driving force for ATP synthesis with the latter strictly dependent on Na+. These results are indicative for the presence of a Na+‐translocating ATP synthase in A. woodii.Keywords
