Small Molecule Inhibitors of Bacterial Quorum Sensing and Biofilm Formation
, 2016 Bacteria monitor their local population densities using small molecules (or autoinducers) in a process known as quorum sensing. Here, we report a new and efficient synthetic route to naturally occurring bacterial autoinducers [N-acyl l-homoserine ...

A structural perspective on the mechanisms of quorum sensing activation in bacteria
Anais da Academia Brasileira de Ciências, 2015 Bacteria are able to synchronize the population behavior in order to regulate gene expression through a cell-to-cell communication mechanism called quorum sensing.

, 2010 Autoinducer regulation of gene expression is thought to coordinate homogeneous cellular activity within a population in a cell density dependent way, called quorum sensing.

Frontiers in Microbiology, 2016 Quorum sensing (QS) is a widespread intercellular form of communication to coordinate physiological processes and cooperative activities of bacteria at the population level, and it depends on the production, secretion, and detection of small diffusible ...

Quorum sensing intervened bacterial signaling: Pursuit of its cognizance and repression
Journal of Genetic Engineering and Biotechnology, 2018 Bacteria communicate within a system by means of a density dependent mechanism known as quorum sensing which regulate the metabolic and behavioral activities of a bacterial community.

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.

Quorum sensing signal–response systems in Gram-negative bacteria
, 2016 Bacteria use quorum sensing to orchestrate gene expression programmes that underlie collective behaviours. Quorum sensing relies on the production, release, detection and group-level response to extracellular signalling molecules, which are called ...

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.

The Vibrio harveyi Master Quorum-sensing Regulator, LuxR, a TetR-type Protein is Both an Activator and a Repressor: DNA Recognition and Binding Specificity at Target Promoters [PDF]
, 2011 Quorum sensing is the process of cell-to-cell communication by which bacteria communicate via secreted signal molecules called autoinducers. As cell population density increases, the accumulation of autoinducers leads to co-ordinated changes in gene ...
