The structure of LsrB from Yersinia pestis complexed with autoinducer-2 [PDF]
The crystal structure of LsrB from Yersinia pestis complexed with autoinducer-2 (AI-2; space group P212121, unit-cell parameters a = 40.61, b = 61.03, c = 125.23 Å) has been solved by molecular replacement using the structure of LsrB from Salmonella typhimurium (PDB entry 1tjy) and refined to R = 0.180 (R free = 0.213) at 1.75 Å ...

Phosphorylation and Processing of the Quorum-Sensing Molecule Autoinducer-2 in Enteric Bacteria [PDF]
Quorum sensing is a process of chemical communication that bacteria use to assess cell population density and synchronize behavior on a community-wide scale. Communication is mediated by signal molecules called autoinducers. The LuxS autoinducer synthase produces 4,5-dihydroxy-2,3-pentanedione (DPD), the precursor to a set of interconverting molecules ...

The Primary Physiological Roles of Autoinducer 2 in Escherichia coli Are Chemotaxis and Biofilm Formation. [PDF]
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

Autoinducer-2 May Be a New Biomarker for Monitoring Neonatal Necrotizing Enterocolitis. [PDF]
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.
