TorR + ATP
?
TorS is a sensor that contains three phosphorylation sites and transphosphorylates TorR via a four-step phosphorelay, His443 to Asp723 to His850 to Asp(TorR). TorS can dephosphorylate phospho-TorR when trimethylamine N-oxide is removed. Dephosphorylation probably occurs by a reverse phosphorelay, Asp(TorR) to His850 to Asp723

ArcA + ATP
?
the ArcB and ArcA proteins constitute a two-component signal transduction system that plays a broad role in transcriptional regulation.

regulation of the levels of OmpF and OmpC is normally controlled by a multicomponent signal-transducing regulatory pair of proteins, EnvZ and OmpR. The effect RprX and RprY have on OmpF expression is mediated at the level of transcription. Thus, RprX and RprY may be interfering with the normal regulation of OmpF by OmpR and EnvZ

a complex of the proteins CheA (CheAL and CheAS) and CheW constitutes a functional unit that responds to the signaling state of the chemoreceptors. The autophosphorylation rate of CheAL is much greater when CheAL and CheAS are complexed with CheW. Moreover, the presence of mutant chemoreceptors that cause cells to tumble increases this rate. At wild-type levels of expression, the isolated CheAL/CheAS/CheW complex accounts for about 10% of the total number of CheAL, CheAS, and CheW molecules and exists in a 1:1:1 stoichiometry. This complex is also required for CheAL/CheAS and CheW binding to the phosphorylation substrate, CheY

expression of cusC is induced by high concentrations of copper ions, the cusRS two-component signal transduction system is required for copper-induced expression of pcoE, a plasmid-borne gene from the E. coli copper resistance operon pco. The genes cusRS are also required for the copper-dependent expression of at least one chromosomal gene, designated cusC, which is allelic to the recently identified virulence gene ibeB in E. coli K1. The cus locus may comprise a copper ion efflux system
