Crystal structure of the sodium-proton antiporter NhaA dimer and new mechanistic insights

A new crystal structure of the Escherichia coli NhaA dimer reveals a previously unidentified salt bridge between two highly conserved residues at the putative binding site. The combination of structural data with molecular dynamics simulations yields new insights into the transport mechanism.
