The Ec-NhaA antiporter switches from antagonistic to synergistic antiport upon a single point mutation
The Na(+), Li(+)/H(+) antiporter of Escherichia coli (Ec-NhaA) maintains pH, Na(+) homeostasis in enterobacteria. We used isothermal titration calorimetry to perform a detailed thermodynamic analysis of Li(+) binding to Ec-NhaA and several of its mutants. We found that, in line with the canonical al...
