Clostridioides difficile LuxS mediates inter-bacterial interactions within biofilms [PDF]
The anaerobic gut pathogen, Clostridioides difficile, forms adherent biofilms that may play an important role in recurrent C. difficile infections. The mechanisms underlying C.

2D proteome analysis initiates new Insights on the
Background Quorum sensing is a term describing a bacterial communication system mediated by the production and recognition of small signaling molecules. The LuxS enzyme, catalyzing the synthesis of AI-2, is conserved in a wide diversity of bacteria. AI-2

Bifidobacteria exhibit LuxS-dependent autoinducer 2 activity and biofilm formation. [PDF]
Autoinducer-2 (AI-2) molecules are one class of signalling molecules involved in gene regulation dependent on population density in a mechanism commonly referred to as quorum sensing (QS).

Uncovering the link between the SpnIII restriction modification system and LuxS in Streptococcus pneumoniae meningitis isolates [PDF]
Streptococcus pneumoniae is capable of randomly switching their genomic DNA methylation pattern between six distinct bacterial subpopulations (A-F) via recombination of a type 1 restriction-modification locus, spnIII.

The Impairment of Methyl Metabolism From luxS Mutation of Streptococcus mutans [PDF]
The luxS gene is present in a wide range of bacteria and is involved in many cellular processes. LuxS mutation can cause autoinducer(AI)-2 deficiency and methyl metabolism disorder. The objective of this study was to demonstrate that, in addition to AI-2-

LuxS-independent formation of AI-2 from ribulose-5-phosphate [PDF]
Background In many bacteria, the signal molecule AI-2 is generated from its precursor S-ribosyl-L-homocysteine in a reaction catalysed by the enzyme LuxS.

Helicobacter pylori luxS mutants cause hyperinflammatory responses during chronic infection [PDF]
Helicobacter pylori infects roughly half the world’s population, causing gastritis, peptic ulcers, and gastric cancer in a subset. These pathologies occur in response to a chronic inflammatory state, but it is not fully understood how H.
