Targeting Bacterial Communication: Evaluating Phytochemicals as LuxS Inhibitors to Disrupt Quorum Sensing

Macromol
Bacterial quorum sensing (QS) is a critical communication process that regulates gene expression in response to population density, influencing activities such as biofilm formation, virulence, and antibiotic resistance.

Regulation of osmoadaptation in the moderate halophile Halobacillus halophilus : chloride, glutamate and switching osmolyte strategies [PDF]

, 2008
The moderate halophile Halobacillus halophilus is the paradigm for chloride dependent growth in prokaryotes. Recent experiments shed light on the molecular basis of the chloride dependence that is reviewed here.

The Crystal Structure of the Escherichia coli Autoinducer-2 Processing Protein LsrF

PLoS ONE, 2009
Many bacteria produce and respond to the quorum sensing signal autoinducer-2 (AI-2). Escherichia coli and Salmonella typhimurium are among the species with the lsr operon, an operon containing AI-2 transport and processing genes that are up regulated in response to AI-2.

Quorumpeps database : chemical space, microbial origin and functionality of quorum sensing peptides [PDF]

, 2012
Quorum-sensing (QS) peptides are biologically attractive molecules, with a wide diversity of structures and prone to modifications altering or presenting new functionalities. Therefore, the Quorumpeps database (http://quorumpeps.ugent.be) is developed to

Norepinephrine may promote the progression of Fusobacterium nucleatum related colorectal cancer via quorum sensing signalling

Virulence
Fusobacterium nucleatum (F. nucleatum) is closely correlated with tumorigenesis in colorectal cancer (CRC). We aimed to investigate the effects of host norepinephrine on the carcinogenicity of F. nucleatum in CRC and reveal the underlying mechanism.

Detection of AI-2 Receptors in Genomes of <em>Enterobacteriaceae </em>Suggests a Role of Type-2 Quorum Sensing in Closed Ecosystems

Sensors, 2012
The LuxS enzyme, an S-ribosyl-homocysteine lyase, catalyzes the production of the signal precursor for autoinducer-2 mediated quorum sensing (QS-2) in <em>Vibrio</em>.

Effects of vitamin B12 supply on cellular processes of the facultative vitamin B12 consumer Vibrio campbellii

Applied and Environmental Microbiology
Vitamin B12 (cobalamin, herein B12) is a key cofactor for most organisms being involved in essential metabolic processes. In microbial communities, B12 is often scarce, largely because only few prokaryotes can synthesize B12 de novo and are thus ...

Single-cell growth kinetic behavior of pathogenic bacteria in the presence of microbial supernatants containing autoinducer-2 signal compounds [PDF]

, 2015
The findings of this study constitute preliminary data on the role of QS compounds on the single-cell growth behavior of important pathogens, knowledge that maybe useful in understanding the mechanisms underlying their behavior as well as in developing ...
