Multiple pathways for regulation of σ S (RpoS) stability in Escherichia coli via the action of multiple anti‐adaptors

SigmaS, the stationary phase sigma factor of Escherichia coli and Salmonella, is regulated at multiple levels. The sigmaS protein is unstable during exponential growth and is stabilized during stationary phase and after various stress treatments. Degradation requires both the ClpXP protease and the ...
