Evidence for extracellular control of RpoS proteolysis in Escherichia coli.

FEMS microbiology letters - 1 Sept 2008

Holland Anne-Marie, Rather Philip N

Abstract excerpt

The RpoS sigma factor is required for the transition of Escherichia coli into stationary phase, as well as adaptation to environmental stresses and nutrient depletion. In this study, we report that under nutrient poor conditions, RpoS protein accumulation in E. coli was strongly enhanced by a secreted factor. Expression of a single copy RpoS'-'LacZ translational fusion was activated 12-fold by the signal, but a...
