Physiological role of the chaA gene in sodium and calcium circulations at a high pH in Escherichia coli.

Journal of bacteriology - 1 Jul 1994

Ohyama T, Igarashi K, Kobayashi H

Abstract excerpt

Ohyama et al. previously isolated Escherichia coli mutant RS1, which had a negligible activity for sodium ion extrusion at alkaline pH (T. Ohyama, R. Imaizumi, K. Igarashi, and H. Kobayashi, J. Bacteriol. 174:7743-7749, 1992). Our present study showed that the mutation of RS1 was compensated for by a cloned chaA gene. It has been proposed that sodium ion extrusion by ChaA is prevented under physiological...
