== Function ==
[https://www.uniprot.org/uniprot/NHAA_ECOLI NHAA_ECOLI] Na(+)/H(+) antiporter that extrudes sodium in exchange for external protons. Catalyzes the exchange of 2 H(+) per Na(+). Can mediate sodium uptake when a transmembrane pH gradient is applied. Active at alkaline pH. Activity is strongly down-regulated below pH 6.5.<ref>PMID:1645730</ref>
