Interaction Information:

Comment P. aeruginosa has developed a mechanism to coordinate expression of genes important for adaptation to the environment. This response is controlled by quorum-sensing systems. Quorum-sensing signaling molecules are acyl homoserine lactones (AHL), which are freely diffusible. When a threshold AHL concentration is reached, AHL binds LasR/RhlR transcriptional activators to induce expression of certain genes. P. aeruginosa predominately makes two autoinducers: N-3-oxododecanoyl homoserine lactone (3-O-C12-HSL, also called PAI-1) and N-butyryl-L-homoserine lactone (C4-HSL, also called PAI-2).
