A Model-Structure of a Periplasm-facing State of the NhaA Antiporter Suggests the Molecular Underpinnings of pH-induced Conformational Changes

The Escherichia coli NhaA antiporter couples the transport of H(+) and Na(+) (or Li(+)) ions to maintain the proper pH range and Na(+) concentration in cells. A crystal structure of NhaA, solved at pH 4, comprises 12 transmembrane helices (TMs), arranged in two domains, with a large cytoplasm-facing...
