Simplified schematic of quorum sensing in V. cholerae. In the absence of an agonist (i.e. at low cell density), CqsS acts as a kinase and virulence factors are expressed. When CqsS binds an agonist (stars), such as at high cell density with higher concentrations of the native agonist CAI-1 and Ea-CAI-1, CqsS acts as a phosphatase, repressing the expression of virulence factors.
