CC -!- FUNCTION: Provides the crucial link between the upstream module
CC (communication of environmental stress) and the downstream module
CC (integration of the environmental signals with signals of energy
CC stress) that compose the signal transduction pathway controlling the
CC sigma-B factor. Phosphorylates and inactivates its specific antagonist
CC protein RsbS thanks to its serine kinase activity. Upon phosphorylation
CC of RsbS, RsbT is released to stimulate RsbU, a PP2C phosphatase,
CC thereby initiating the signaling cascade that ultimately activates
CC sigma-B. The activity of the RsbU phosphatase may be stimulated by a
CC long-lived interaction with RsbT and the serine kinase function of RsbT
CC is not required to directly modify RsbU. Also phosphorylates RsbR
CC thanks to its threonine kinase activity, preventing it to phosphorylate
CC RsbT. {ECO:0000269|PubMed:8824586, ECO:0000269|PubMed:9786195}.
