DivL protein is homologous to the ubiquitous bacterial histidine protein kinases, it differs from previously studied members of this protein kinase family in that it contains a tyrosine residue Tyr550 in the conserved H-box instead of a histidine residue, which is the expected site of autophosphorylation. DivL is autophosphorylated on Tyr-550 in vitro, and this tyrosine residue is essential for cell viability and regulation of the cell division cycle

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

A two-component system comprises a histidine kinase protein or sensor mostly inserted into the inner membrane and a cognate partner known as the response regulator. The stimulus by the periplasmic or cytoplasmic detection domain of the histidine kinase protein triggers autophosphorylation on a conserved histidine residue of the transmitter domain H1. The phosphoryl group is then transferred on a conserved aspartate residue present in the receiver or D domain of the cognate response regulator. In Pseudomonas aeruginosa, the histidine kinase requires additional domains such as a receiver domain (D1) fused to the histidine kinase. Two-component system mechanism, overview
