The strict anaerobic bacterium Propionigenium modestum performs a Na+ cycle over the membrane to couple ATP synthesis to the decarboxylation of methyl-malonyl-CoA. The responsible ATPase has a typical F1F0 structure, the water-soluble F1 moiety being composed of five different subunits and the more firmly membrane-bound F0 part consisting of three different… (More)
