The phosphoryl group is then transferred on Asp-771 of the response regulator domain. The phosphoryl group is transferred to LuxU, and ultimately to LuxO. At high cell density, in the presence of AI-1, the kinase activity is inactivated, and the response regulator domain has a phosphatase activity. LuxN phosphatase acts on itself.

cqsS | luxO | AL538_23270 | AL538_04125 | Hybrid sensor histidine kinase/response regulator; Derived by automated computational analysis using gene prediction method: Protein Homology. | AAA family ATPase; Acts negatively to control the expression of luminescence. At low cell density, LuxO is phosphorylated, and together with sigma-54, causes repression of the luxCDABEGH operon. This repression could be indirect, LuxO could activate a negative regulator of luminescence. At high cell density, LuxO is dephosphorylated and inactive, therefore the luxCDABEGH operon is not repressed and light is emitted. LuxO and sigma-54 have also a role in activating the production of siderophore and in regulating the rugose colony morphology phenotype (By similarity). | 0.508 |

cqsS | luxS | AL538_23270 | AL538_06575 | Hybrid sensor histidine kinase/response regulator; Derived by automated computational analysis using gene prediction method: Protein Homology. | S-ribosylhomocysteinase; Involved in the synthesis of autoinducer 2 (AI-2) which is secreted by bacteria and is used to communicate both the cell density and the metabolic potential of the environment. The regulation of gene expression in response to changes in cell density is called quorum sensing.

LuxN and LuxP transfer a phosphoryl group to LuxU on His-58 and this phosphoryl group is further transferred to LuxO. At high cell density, as LuxU could function to establish an equilibrium between the aspartyl-phosphate of LuxN and the aspartyl-phosphate of LuxO, LuxU transfers phosphate from LuxO to LuxN (and probably LuxP) and finally phosphate is drained from the system. | 0.991 |
