摘要：

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 DELTA-pH, indicating the presence of a proton-translocating ATPase. On the other hand, a DELTA-pNa, 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.
