【 摘 要 】

The Na⁺-translocating F₁F₀-ATPase of Acetobacterium woodii was examined by electron microscopy. After reconstitution into proteoliposomes, knobs typical for the F₁ domain were visible on the outside of the membrane. The F₁-part of the isolated enzyme showed a hexagonal symmetry suggesting an α₃β₃ structure, and the F₁F₀ complex had molecular dimensions very similar to those of H⁺-translocating ATPases of E. coli, chloroplasts, and mitochondria.
