Representative QS systems of Gram-negative (A) and Gram-positive (B) bacteria

Caption

Representative QS systems of Gram-negative (A) and Gram-positive (B) bacteria. For Gram-negative bacteria, the AIs are AHLs, which are encoded by luxI. Upon reaching a threshold, AHLs bind to LuxR, subsequently activating the expression of genes involved in the production of virulence factors. For Gram-positive bacteria, the AIs are AIP, which is encoded by argD. Upon reaching a threshold, AIP binds to ArgC, subsequently activating the expression of virulence-related genes.
