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

Autoinducer-2 Facilitates Pseudomonas aeruginosa PAO1 Pathogenicity in Vitro and in Vivo [PDF]
Frontiers in Microbiology, 2017 Bacterial communication systems, such as quorum sensing (QS), have provided new insights of alternative approaches in antimicrobial treatment. We recently reported that one QS signal, named as autoinducer-2 (AI-2), can affect the behaviors of Pseudomonas

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 ...

Making 'sense' of metabolism: autoinducer-2, LUXS and pathogenic bacteria [PDF]
Nature Reviews Microbiology, 2005 Bacteria exploit many mechanisms to communicate with each other and their surroundings. Mechanisms using small diffusible signals to coordinate behaviour with cell density (quorum sensing) frequently contribute to pathogenicity. However, pathogens must also be able to acquire nutrients and replicate to successfully invade their host. One quorum-sensing

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
