Importance of RpoS and Dps in survival of exposure of both exponential- and stationary-phase Escherichia coli cells to the electrophile N-ethylmaleimide.

Abstract excerpt

The mechanisms by which Escherichia coli cells survive exposure to the toxic electrophile N-ethylmaleimide (NEM) have been investigated. Stationary-phase E. coli cells were more resistant to NEM than exponential-phase cells. The KefB and KefC systems were found to play an important role in protecting both exponential- and stationary-phase cells against NEM. Additionally, RpoS and the DNA-binding protein Dps aided...
