Osmotic signal transduction to proU is independent of DNA supercoiling in Escherichia coli.

Journal of bacteriology - 1 Jan 1991

Ramirez R M, Villarejo M

Abstract excerpt

proU expression has been proposed to form part of a general stress response that is regulated by increased negative DNA supercoiling brought about by environmental signals such as osmotic or anaerobic stress (N. Ni Bhriain, C. J. Dorman, and C. F. Higgins, Mol. Microbiol. 3:933-944, 1989). However, we find that although proU-containing plasmids derived from cells grown in media of elevated osmolarity were more...
