Maintenance of Microbial Cooperation Mediated by Public Goods in Single- and Multiple-Trait Scenarios [PDF]

, 2017
Microbes often form densely populated communities, which favor competitive and cooperative interactions. Cooperation among bacteria often occurs through the production of metabolically costly molecules produced by certain individuals that become ...

LuxS influencesEscherichia colibiofilm formation through autoinducer-2-dependent and autoinducer-2-independent modalities [PDF]

FEMS Microbiology Ecology, 2012
Escherichia coli produces biofilms in response to the small molecule autoinducer-2 (AI-2), a product of the LuxS enzyme. LuxS is part of the activated methyl cycle and could also affect biofilm development by AI-2-independent effects on metabolism. A luxS deletion mutant of E.

Genetic and functional characterization of the gene cluster directing the biosynthesis of putisolvin I and II in Pseudomonas putida strain PCL1445 [PDF]

, 2008
Pseudomonas putida PCL1445 secretes two cyclic lipopeptides, putisolvin I and putisolvin II, which possess a surface-tension-reducing ability, and are able to inhibit biofilm formation and to break down biofilms of Pseudomonas species including ...

Detection of AI-2 Receptors in Genomes of <em>Enterobacteriaceae </em>Suggests a Role of Type-2 Quorum Sensing in Closed Ecosystems

Sensors, 2012
The LuxS enzyme, an S-ribosyl-homocysteine lyase, catalyzes the production of the signal precursor for autoinducer-2 mediated quorum sensing (QS-2) in <em>Vibrio</em>.

Frequency modulation of a bacterial quorum sensing response

Nature Communications, 2022
Quorum-sensing bacteria produce and secrete autoinducers that trigger a behavioral change in the population when reaching a certain threshold. Here, Bettenworth et al.

Identification of Functional LsrB-Like Autoinducer-2 Receptors [PDF]

Journal of Bacteriology, 2009
ABSTRACTAlthough a variety of bacterial species have been reported to use the interspecies communication signal autoinducer-2 (AI-2) to regulate multiple behaviors, the molecular mechanisms of AI-2 recognition and signal transduction remain poorly understood.

Plant-Derived Natural Products as Sources of Anti-Quorum Sensing Compounds

Sensors, 2013
Quorum sensing is a system of stimuli and responses in relation to bacterial cell population density that regulates gene expression, including virulence determinants. Consequently, quorum sensing has been an attractive target for the development of novel

Global convergence of quorum-sensing networks [PDF]

, 2010
In many natural synchronization phenomena, communication between individual elements occurs not directly, but rather through the environment. One of these instances is bacterial quorum sensing, where bacteria release signaling molecules in the ...

Processing The Interspecies Quorum-Sensing Signal Autoinducer-2 (AI-2) Characterization Of Phospho-(S)-4,5-Dihydroxy-2,3-Pentanedione Isomerization By LsrG Protein [PDF]

, 2011
The molecule (S)-4,5-dihydroxy-2,3-pentanedione (DPD) is produced by many different species of bacteria and is the precursor of the signal molecule autoinducer-2 (AI-2).
