Abstrakt

This review discusses the progress of bioenergetic studies on the role of Na+ in bacteria and Archaea. Na+ ions have at least four functions in bacterial and Archaeal cells, namely in the Na+- ion X cotransport system, Na+-coupled energy transformation, pH homeostasis mechanisms, and activation of special enzymes. Thus, in a number of bacteria and Archaea, endergonic and the exergonic membrane-associated processes are linked by the cycling of Na+ ions which shows that Na+, under certain conditions, can substitute H+ as the coupling ions. This review also discusses some problems related to the Na+ cycle in human pathogens.
