What is Na^+^‐coupled alternative to H^+^‐coupled primary transport systems in bacteria about?
## Abstract Protons are the most common coupling ions in bacterial energy conversions. However, while many organisms, such as the alkaliphilic Bacilli, employ H^+^‐bioenergetics for electron transport phosphorylation, they use Na^+^ as the coupling ion for transport and flagellar movement. The Na^+^ gradient required for these bioenergetic functions is established by the secondary Na^+^/H^+^ antiporter. In contrast, __Vibrio alginolyticus__ and methanogenic bacteria have primary pumps for both H^+^ and Na^+^. They use the proton gradient for ATP synthesis while other, less energy‐consuming membrane reactions are powered by the Na^+^ gradient. In a third mode, some anaerobic bacteria possess decarboxylases acting as primary Na^+^ pumps. For instance, in __Klebsiella pneumoniae__, the Na^+^ gradient established by oxaloacetate decarboxylase is used for the uptake of the growth substrate citrate, and __Propionigenium modestum__ consumes the energy of the Na^+^ gradient formed by methylmalonyl‐CoA decarboxylase directly for ATP synthesis.
