Structure, Regulation, and Inhibition of the Quorum-Sensing Signal Integrator LuxO.

open access: yesPLoS Biology, 2016
In a process called quorum sensing, bacteria communicate with chemical signal molecules called autoinducers to control collective behaviors. In pathogenic vibrios, including Vibrio cholerae, the accumulation of autoinducers triggers repression of genes ...

A Tale of Two Theories: Using an Engineered Strain of E. coli to Bridge the Gap Between Quorum Sensing and Diffusion Sensing [PDF]

open access: yes, 2016
Cooperation is a trait that is found at all levels of biological organization. Interestingly, cooperation appears to occur in bacteria that produce small, easily diffusible molecules called autoinducers.

ThePseudomonas aeruginosaLasR quorum-sensing receptor balances ligand selectivity and sensitivity

open access: yes, 2018
Quorum sensing is a cell-cell communication process that bacteria use to orchestrate group behaviors. Quorum sensing is mediated by extracellular signal molecules called autoinducers.

Asymmetric regulation of quorum-sensing receptors drives autoinducer-specific gene expression programs in Vibrio cholerae.

open access: yesPLoS Genetics, 2017
Quorum sensing (QS) is a mechanism of chemical communication that bacteria use to monitor cell-population density and coordinate group behaviors. QS relies on the production, detection, and group-wide response to extracellular signal molecules called ...

α-Hydroxyketone Synthesis and Sensing by Legionella and Vibrio

open access: yesSensors, 2012
Bacteria synthesize and sense low molecular weight signaling molecules, termed autoinducers, to measure their population density and community complexity. One class of autoinducers, the α-hydroxyketones (AHKs), is produced and detected by the water-borne

Stabilization of enzymes by dormancy autoinducers as a possible mechanism of resistance of resting microbial forms

open access: yes, 2020
Alkyl-substituted hydroxybenzenes (AHBs), autoinducers of microbial dormancy (or d1 factors), were found to stabilize the structure of protein macromolecules, making them metabolically less active and more resistant to stresses. In vitro experiments with

Characteristics of the Pseudomonas aeruginosa PA01 Intercellular Signaling Pathway (Quorum Sensing) Functioning in Presence of Porphyrins Bismuth Complexes

open access: yes, 2015
The influence of synthetic and natural porphyrins bismuth complexes on P. aeruginosa quorum sensing system was carried out by detection of the pyocyanin, rhamnolipids and autoinducers biosynthesis level.

Effects of various concentrations of HAI-1 and AI-2 on LuxN- and LuxQ- mediated phosphorylation of LuxU.

open access: yes, 2013
LuxN- and LuxQ-bearing membrane vesicles, together with purified LuxP and LuxU, were incubated with 100 μM [γ-32P] ATP, and the effects of AI-2 and HAI-1 on the initial rate of LuxU phosphorylation were tested.

Modeling captures the social interactions in the B. subtilis ComA network.

open access: yes, 2016
(A) Modeling results for the fitness advantage of the ExtraRap and ExtraCom strains over the wild-type. Shown in insets are schemes of the social interactions in the extreme cases in which one of the strains is a small minority. Arrow sizes represent the
