Mechanism of Vibrio cholerae Autoinducer-1 Biosynthesis

ACS Chemical Biology, 2011
Vibrio cholerae, the causative agent of the disease cholera, uses a cell to cell communication process called quorum sensing to control biofilm formation and virulence factor production. The major V. cholerae quorum-sensing signal CAI-1 has been identified as (S)-3-hydroxytridecan-4-one, and the CqsA protein is required for CAI-1 production.

Molecular radio jamming: autoinducer analogs.

Chemistry & biology, 2003
Synthesis of an N-acyl-homoserine lactone (N-acyl-HSL) analog library yields agonists and antagonists of the Pseudomonas aeruginosa quorum-sensing system. Active compounds also reveal heterogeneity in the lactone ring binding pockets of N-acyl-HSL-activated transcription factors.

Controlling the activity of quorum sensing autoinducers with light

Chemical Science, 2015
Bacteria use Quorum Sensing (QS) to organize into communities and synchronize gene expression. Here we report on a method to externally interfere with QS system using light.

Single cell analysis of Vibrio harveyi uncovers functional heterogeneity in response to quorum sensing signals

BMC Microbiology, 2012
Background Vibrio harveyi and closely related species are important pathogens in aquaculture. A complex quorum sensing cascade involving three autoinducers controls bioluminescence and several genes encoding virulence factors. Single cell analysis of a V.

Information processing and signal integration in bacterial quorum sensing

Molecular Systems Biology, 2009
Bacteria communicate using secreted chemical signaling molecules called autoinducers in a process known as quorum sensing. The quorum‐sensing network of the marine bacterium Vibrio harveyi uses three autoinducers, each known to encode distinct ecological
