A global perspective on autoinducer-2-mediated cell communication in prokaryotes [PDF]

iScience
Summary: Animal communication within a community is essential for their survival and reproduction. This phenomenon is not restricted to animals but is also prevalent in prokaryotes, which employ quorum sensing (QS) mechanisms for communication and ...

New Insights into Autoinducer-2 Signaling as a Virulence Regulator in a Mouse Model of Pneumonic Plague [PDF]

mSphere, 2016
The Enterobacteriaceae family members, including the infamous Yersinia pestis, the causative agent of plague, have a highly conserved interbacterial signaling system that is mediated by the autoinducer-2 (AI-2) quorum-sensing molecule. The AI-2 system is

ArcB initiates quorum sensing to regulate T3SS in Vibrio alginolyticus by recognizing bacterial and host-derived autoinducer-2 as a kinase [PDF]

Cell Communication and Signaling
Background The marine pathogen Vibrio alginolyticus employs its type III secretion system (T3SS), a syringe-like secretion apparatus, to kill eukaryotic cells.

Autoinducer-2 Could Affect Biofilm Formation by Food-Derived Bacillus cereus. [PDF]

Indian J Microbiol, 2021
Bacillus cereus is a foodborne pathogen and cause a frequent problem due to the biofilms forming in equipment of food production plants. Autoinducer-2 (AI-2) involved in interspecies communication, plays a role in the biofilm formation of B. cereus. In this study, biofilm formation by thirty-nine B.

Autoinducer 2 Affects Biofilm Formation byBacillus cereus [PDF]

Applied and Environmental Microbiology, 2006
ABSTRACTCell-free supernatants from growingBacillus cereusstrain ATCC 10987 induced luminescence in aPhotorhabdus luminescensΔluxSmutant, indicating the production of functional autoinducer 2 (AI-2). The exogenous addition of in vitro synthesized AI-2 had an inhibitory effect on biofilm formation byB.

The Janthinobacterium sp. HH01 genome encodes a homologue of the V. cholerae CqsA and L. pneumophila LqsA autoinducer synthases [PDF]

, 2013
Janthinobacteria commonly form biofilms on eukaryotic hosts and are known to synthesize antibacterial and antifungal compounds. Janthinobacterium sp. HH01 was recently isolated from an aquatic environment and its genome sequence was established.

Autoinducer-2-mediated communication network within human gut microbiota. [PDF]

ISME J
Abstract Quorum sensing (QS) is a chemical communication process that connects microbial members in various microbial systems. Bacterial communication networks mediated by QS play important roles in the regulation of intestinal microecological balance as well as nutrition and metabolism of the host.

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 ...

ML364 exerts the broad-spectrum antivirulence effect by interfering with the bacterial quorum sensing system

Frontiers in Microbiology, 2022
Antivirulence strategy has been developed as a nontraditional therapy which would engender a lower evolutionary pressure toward the development of antimicrobial resistance.

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 ...
