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.
两种单价离子转运蛋白，即平腹肠球菌假定的Na⁺/H⁺反向转运蛋白（NapA）和大肠杆菌假定的K⁺/H⁺反向转运蛋白（KefC），在其整个疏水结构域的序列上相似。这两种蛋白质构成了一个与大肠杆菌先前鉴定的Na⁺/H⁺交换蛋白（NhaA和NhaB）无关的新型转运蛋白家族，它们被认为通过基本相同的机制发挥作用。
