The response regulator RssB, a recognition factor for sigmaS proteolysis in Escherichia coli, can act like an anti-sigmaS factor.

Molecular microbiology - 1 Feb 2000

Becker G, Klauck E, Hengge-Aronis R

Abstract excerpt

sigmaS (RpoS) is the master regulator of the general stress response in Escherichia coli. Several stresses increase cellular sigmaS levels by inhibiting proteolysis of sigmaS, which under non-stress conditions is a highly unstable protein. For this ClpXP-dependent degradation, the response regulator RssB acts as a recognition factor, with RssB affinity for sigmaS being modulated by phosphorylation. Here, we...
