描述 | Quorum sensing is a regulatory system used by bacteria for controlling gene expression in response to increasing cell density.1 This regulatory process manifests itself with a variety of phenotypes including biofilm formation and virulence factor production.2 Coordinated gene expression is achieved by the production, release, and detection of small diffusible signal molecules called autoinducers. The N-acylated homoserine lactones (AHLs) comprise one such class of autoinducers, each of which generally consists of a fatty acid coupled with homoserine lactone (HSL). Regulation of bacterial quorum sensing signaling systems to inhibit pathogenesis represents a new approach to antimicrobial therapy in the treatment of infectious diseases.3 AHLs vary in acyl group length (C4-C18), in the substitution of C3 (hydrogen, hydroxyl, or oxo group), and in the presence or absence of one or more carbon-carbon double bonds in the fatty acid chain. These differences confer signal specificity through the affinity of transcriptional regulators of the LuxR family.4 In one of the most-studied quorum-sensing systems in gram-negative bacteria, the LuxI AHL synthase catalyzes the production of N-(β-ketocaproyl)-L-homoserine lactone utilizing S-adenosylmethionine and hexanoyl-acyl carrier protein as reaction substrates in the marine bioluminescence bacterium V. fischeri.5 At increased populations of the bacteria, localized higher concentrations of 3-O-C6-HSL, an endogenous ligand to transcriptional factor LuxR, leads to increased production of both the AHL synthase and proteins responsible for bioluminescence.1 Numerous other species of bacteria also employ N-(β-ketocaproyl)-L-homoserine lactone in cell-to-cell communication.6,7,8,9 |
