Abstract excerpt

Cells of the E. coli mutant EP432, which lacks the two Na+/H+ antiporters, NhaA and NhaB, have been reported to have an impaired sodium transport activity (Harel-Bronstein et al. (1995) J. Biol. Chem. 270, 3816-3822). Here we report that active transport of Na+ in EP432 cells can be restored to w...
