AI-2-mediated signalling in bacteria [PDF]
FEMS Microbiology Reviews, 2013 Success in nature depends upon an ability to perceive and adapt to the surrounding environment. Bacteria are not an exception; they recognize and constantly adjust to changing situations by sensing environmental and self-produced signals, altering gene expression accordingly.

AI-2-dependent gene regulation in Staphylococcus epidermidis [PDF]
BMC Microbiology, 2008 Abstract Background Autoinducer 2 (AI-2), a widespread by-product of the LuxS-catalyzed S-ribosylhomocysteine cleavage reaction in the activated methyl cycle, has been suggested to serve as an intra- and interspecies signaling molecule, but in many bacteria AI-2 control of gene expression is not completely understood.

Chemotaxis to the Quorum-Sensing Signal AI-2 Requires the Tsr Chemoreceptor and the Periplasmic LsrB AI-2-Binding Protein [PDF]
Journal of Bacteriology, 2011 ABSTRACTAI-2 is an autoinducer made by many bacteria. LsrB binds AI-2 in the periplasm, and Tsr is thel-serine chemoreceptor. We show that AI-2 strongly attractsEscherichia coli. Both LsrB and Tsr are necessary for sensing AI-2, but AI-2 uptake is not, suggesting that LsrB and Tsr interact directly in the periplasm.

A Multivalent Probe for AI-2 Quorum-Sensing Receptors [PDF]
Journal of the American Chemical Society, 2011 Multivalency is a common principle in the recognition of cellular receptors, and multivalent agonists and antagonists have played a major role in understanding mammalian cell receptor biology. The study of bacterial cell receptors using similar approaches, however, has lagged behind.

Discovery of a Human Metabolite That Mimics the Bacterial Quorum-Sensing Autoinducer AI-2. [PDF]
J Am Chem SocBacteria use small molecules to orchestrate collective behaviors in a process called quorum sensing (QS), which relies on the production, release, and group-wide detection of extracellular signal molecules referred to as autoinducers. One QS autoinducer, termed AI-2, is broadly used for inter-species bacterial communication, including in the mammalian ...

Let LuxS speak up in AI-2 signaling [PDF]
Trends in Microbiology, 2006 Quorum sensing is a process of bacterial cell-cell communication that uses small diffusible molecules to coordinate diverse behaviors in response to population density. The only quorum-sensing system shared by Gram-positive and Gram-negative bacteria involves the production of autoinducer-2 (AI-2). The AI-2 synthase LuxS is widely distributed among the
