Na+/H+ antiporter that extrudes sodium in exchange for external protons, NhaB of 500 aas. Can also extrude lithium in exchange for protons.   Km values for Li+ and Na+ of 2.0 mM and 1.3 mM, respectively. The antiport activity was inhibited by amiloride with a Ki value of 0.04 mM (Kuroda et al. 2004).
