| Abstract: | 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. |
