Two monovalent ion porters, the putative Na + /H + antiporter (NapA) of Enterococcus hirae and the putative K + /H + antiporter (KefC) of Escherichia coli , are similar in sequence throughout their hydrophobic domains. These two proteins, which comprise a novel family of transporters unrelated to the previously characterized Na + /H + exchangers of E. coli (NhaA and NhaB) are proposed to function by essentially the same mechanism.
