The Primary Physiological Roles of Autoinducer 2 in Escherichia coli Are Chemotaxis and Biofilm Formation. [PDF]
Microorganisms, 2021 Autoinducer 2 (AI-2) is a ubiquitous metabolite but, instead of acting as a “universal signal,” relatively few phenotypes have been associated with it, and many scientists believe AI-2 is often a metabolic byproduct rather than a signal. Here, the aim is

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 ...

The Autoinducer-2 Exporter Superfamily [PDF]
Microbial Physiology, 2010 The TqsA (YdgG) protein of <i>Escherichia coli</i> has been shown to export the autoinducer-2 (AI-2) molecule, a furanosyl borate diester that bears little resemblance to previously characterized biological molecules. TqsA belongs to a large superfamily, the AI-2 exporter (AI-2E) superfamily, of putative transporters with no other ...

Autoinducer-2 May Be a New Biomarker for Monitoring Neonatal Necrotizing Enterocolitis. [PDF]
Front Cell Infect Microbiol, 2020 El autoinductor-2 (AI-2) tiene un papel ampliamente aceptado en la comunicación bacteriana intra e interespecie. Poco se sabe sobre las relaciones entre AI-2 y NEC. Este estudio encontró que los niveles de AI-2 en pacientes y en un modelo de ratón NEC se detectaron utilizando el sistema de ensayo Vibrio harveyi BB170.

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.

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.
