Transcription profiling of Escherichia coli over-expressing genes involved in signaling systems that detect and respond to alterations of the bacterial envelope

ABSTRACT: The Bae, Cpx, Psp, Rcs and ?E pathways constitute the Escherichia coli signaling systems that detect and respond to alterations of the bacterial envelope. Contributions of these systems to stress response have previously been examined individually; however, the possible interconnections between these pathways are unknown. Here we investigate the dynamics between the five stress response pathways by i) determining the specificities of each system with respect to signal inducing conditions, and ii) monitoring global transcriptional changes in response to transient over-expression of each of the effectors.
