Abstract

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 alpha 3 beta 3 structure, and the F1F0 complex had molecular dimensions very similar to those of H(+)-translocating ATPases of E. coli, chloroplasts, and mitochondria.
