N-acylhomoserine-lactone-mediated communication between Pseudomonas aeruginosa and Burkholderia cepacia in mixed biofilms. [PDF]

Microbiology, 2001
Pseudomonas aeruginosa and Burkholderia cepacia are capable of forming mixed biofilms in the lungs of cystic fibrosis patients. Both bacteria employ quorum-sensing systems, which rely on N-acylhomoserine lactone (AHL) signal molecules, to co-ordinate expression of virulence factors with the formation of biofilms. As both bacteria utilize the same class

Capsular polysaccharide biosynthesis and pathogenicity in Erwinia stewartii require induction by an N-acylhomoserine lactone autoinducer [PDF]

Journal of Bacteriology, 1995
N-Acylhomoserine lactone (acyl-HSL)-mediated gene expression, also called autoinduction, is conserved among diverse gram-negative bacteria. In the paradigm Vibrio fischeri system, bioluminescence is autoinducible, and the lux operon requires the transcriptional activator LuxR and the acyl-HSL autoinducer for expression.

Stereochemical insignificance discovered in Acinetobacter baumannii quorum sensing. [PDF]

PLoS ONE, 2012
Stereochemistry is a key aspect of molecular recognition for biological systems. As such, receptors and enzymes are often highly stereospecific, only recognizing one stereoisomer of a ligand.

N-Acylhomoserine lactone-mediated quorum sensing: a twist in the tail and a blow for host immunity.

Chemistry & Biology, 2008
Communication through quorum sensing (QS) enables bacterial populations to coordinate their behavior. Recent work on N-acylhomoserine lactone-mediated QS has revealed that some soil bacteria exploit host-derived substrates to generate an alternative N-substituted homoserine lactone.

N-acylhomoserine lactone-degrading bacteria isolated from hatchery bivalve larval cultures.

Microbiological Research, 2013
Quorum sensing (QS) systems, which depend on N-acylhomoserine lactone (AHL) signal molecules, mediate the production of virulence factors in many pathogenic microorganisms. One hundred and forty-six bacterial strains, isolated from a bivalve hatchery, were screened for their capacity to degrade five synthetic AHLs [N-butyryl-DL-homoserine lactone (C4 ...

Nocardioides kongjuensis sp. nov., an N-acylhomoserine lactone-degrading bacterium [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2006
A Gram-positive, rod- or coccoid-shaped andN-hexanoyl-l-homoserine lactone-degrading bacterial strain, A2-4T, was isolated from a soil in Korea, and its taxonomic position was investigated by using a polyphasic approach. Strain A2-4Tgrew optimally at pH 7.0–8.0 and 30 °C without NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that

Detection of N-acylhomoserine lactones in lung tissues of mice infected with Pseudomonas aeruginosa [PDF]

Microbiology, 2000
The pathogenesis of Pseudomonas aeruginosa is associated with expression of virulence factors, many of which are controlled by two N:-acylhomoserine lactone (AHL)-based quorum-sensing systems. Escherichia coli strains equipped with a luxR-based monitor system expressing green fluorescent protein (GFP) in the presence of exogenous AHL molecules were ...

Labrenzia sp. BM1: A Quorum Quenching Bacterium That Degrades N-acyl Homoserine Lactones via Lactonase Activity

Sensors, 2014
We report the degradation of quorum sensing N-acylhomoserine lactone molecules by a bacterium isolated from a Malaysian marine water sample. MALDI-TOF and phylogenetic analysis indicated this isolate BM1 clustered closely to Labrenzia sp.
