Regulation of kdp operon expression in Escherichia coli: evidence against turgor as signal for transcriptional control.

Journal of bacteriology - 1 Jul 1993

Asha H, Gowrishankar J

Abstract excerpt

Kdp, an inducible high-affinity K+ transporter in Escherichia coli, is encoded by genes of the kdpABC operon, and its expression is regulated by the products of kdpD and kdpE. Loss of cell turgor has been proposed to be the signal which induces kdp expression (L. A. Laimins, D. B. Rhoads, and W. Epstein, Proc. Natl. Acad. Sci. USA 78:464-468, 1981). We reexamined kdp expression during steady-state growth under a...
