the enzyme is involved in one of the the quorum sensing systems that function in parallel to control the density-dependent expression of the luciferase structural operon luxCDABE. Each system is composed of a sensor, sensor I or sensor 2, and its cognate autoinducer, AI-1 or AI-2. LuxS has a role in the enzymatic synthesis of AI-2 |

LuxS is related on the one hand to down-regulation of competence, and on the other hand to attenuation of autolysis in cultures entering stationary phase. The impact of LuxS on competence, but not on autolysis, involves cel-cell communication |
