A Simple Biosensor-Based Assay for Quantitative Autoinducer-2 Analysis [PDF]
ACS Synthetic Biology, 2022 Bacteria produce and react to interspecies signaling molecules in order to control the expression of genes that are particularly beneficial when they are expressed by a bacterial community. In addition to intraspecies communication, the signaling molecule autoinducer-2 (AI-2) can also serve for interspecies communication between Gram-positive and Gram ...

Roles of autoinducer-2 mediated quorum sensing in wastewater treatment
Water Science and Technology, 2021 Quorum sensing (QS) is considered to be a promising regulation method for biological wastewater treatment (WWT) due to its regulation in extracellular substances (EPS) production, biofilm formation, granulation, colonization and bacterial activity and ...

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.

Design, Synthesis, and Evaluation of Transition-State Analogs as Inhibitors of the Bacterial Quorum Sensing Autoinducer Synthase CepI [PDF]
, 2020 Quorum sensing is a bacterial signaling system that involves the synthesis and detection of small signal molecules called autoinducers. A main class of autoinducers in Gram-negative bacteria are acylated homoserine lactones, produced by the LuxI family ...

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.

alpha-Hydroxyketone Synthesis and Sensing by Legionella and Vibrio [PDF]
, 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

Analysis of autoinducer-2 quorum sensing in Yersinia pestis. [PDF]
Infect Immun, 2013 ABSTRACT The autoinducer-2 (AI-2) quorum-sensing system has been linked to diverse phenotypes and regulatory changes in pathogenic bacteria. In the present study, we performed a molecular and biochemical characterization of the AI-2 system in Yersinia pestis , the causative agent of plague. In strain CO92,
