Escherichia coli K-12 substr. MG1655 Pathway: RcsCDB Two-Component Signal Transduction System

Diagram Key: ?

Genetic Regulation Schematic: ?

Superclasses: Signal transduction pathways

Summary:
In E.coli K-12 the Rcs proteins are involved in a complex phosphorelay system that is believed to play a role in controlling the temporal expression of genes related to biofilm formation and may have a broader role as a global regulator controlling cell surface composition in response to changing environments. Numerous conditions that activate the Rcs phosphorelay have been observed including osmotic shock, dessication and perturbations in the integrity of the cell membrane. The Rcs regulon is large and includes genes for colonic acid capsule synthesis, cell division, motility and membrane lipoproteins.

The Rcs phosphorelay involves three separate proteins: RcsC, RcsD and RcsB. Phosphate transfer occurs from the sensor kinase RcsC, which autophosphorylates in response to an environmental signal, to RcsD and then to the cytoplasmic transcription factor RcsB. RcsB, either alone or in combination with RscA, activates transcription from a wide range of genes, including those for capsule synthesis and some membrane proteins, and it negatively regulates flagella synthesis. An auxillary protein, the outer membrane lipoprotein RcsF, is believed play a role in signal transduction from the cell surface to RscC.
