Escherichia coli is able to grow with negligible sodium ion extrusion activity at alkaline pH.

Journal of bacteriology - 1 Dec 1992

Ohyama T, Imaizumi R, Igarashi K, Kobayashi H

Abstract excerpt

The Escherichia coli mutant NM81, which is deficient in the nhaA gene for the sodium/proton antiporter, still has a sodium ion extrusion activity because of a second antiporter encoded by nhaB (E. Padan, N. Maisler, D. Taglicht, R. Karpel, and S. Schuldiner, J. Biol. Chem. 264:20297-20302, 1989). By chance, we have found that E. coli pop6810 already contains a mutation affecting the sodium ion circulation,...
