Transcriptional and post-transcriptional regulation of the Escherichia coli luxS mRNA; involvement of the sRNA MicA.

PLoS ONE, 2010
BackgroundThe small RNA (sRNA) MicA has been shown to post-transcriptionally regulate translation of the outer membrane protein A (OmpA) in Escherichia coli.

The small regulatory RNA molecule MicA is involved in Salmonella enterica serovar Typhimurium biofilm formation

BMC Microbiology, 2010
Background LuxS is the synthase enzyme of the quorum sensing signal AI-2. In Salmonella Typhimurium, it was previously shown that a luxS deletion mutant is impaired in biofilm formation.

Bifidobacteria exhibit LuxS-dependent autoinducer 2 activity and biofilm formation. [PDF]

PLoS ONE, 2014
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).

Salmonella Typhimurium and Multidirectional Communication in the Gut [PDF]

, 2016
The mammalian digestive tract is home to trillions of microbes, including bacteria, archaea, protozoa, fungi and viruses. In monogastric mammals the stomach and small intestine harbor diverse bacterial populations but are typically less populated than ...

Biomolecular mechanisms of staphylococcal biofilm formation [PDF]

, 2013
The multitude of biomolecular and regulatory factors involved in staphylococcal adhesion and biofilm formation owe much to their ability to colonize surfaces, allowing the biofilm form to become the preferential bacterial phenotype.

Production of FAME biodiesel in E. coli by direct methylation with an insect enzyme. [PDF]

, 2016
Most biodiesel currently in use consists of fatty acid methyl esters (FAMEs) produced by transesterification of plant oils with methanol. To reduce competition with food supplies, it would be desirable to directly produce biodiesel in microorganisms.

The Impairment of Methyl Metabolism From luxS Mutation of Streptococcus mutans

Frontiers in Microbiology, 2018
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-

Deficiency of RgpG causes major defects in cell division and biofilm formation, and deficiency of LytR-CpsAPsr family proteins leads to accumulation of cell wall antigens in culture medium by Streptococcus mutans [PDF]

, 2017
Streptococcus mutans is known to possess rhamnose-glucose polysaccharide (RGP), a major cell wall antigen. S. mutans strains deficient in rgpG , encoding the first enzyme of the RGP biosynthesis

The fitness burden imposed by synthesising quorum sensing signals [PDF]

, 2016
It is now well established that bacterial populations utilize cell-to-cell signaling (quorum-sensing, QS) to control the production of public goods and other co-operative behaviours.
