Genomics Data, 2015 Citrobacter freundii strain ST2, isolated from the algae bloom sample, possesses an N-acylhomoserine lactone (AHL) production activity that secretes short-chain AHL molecules. In this study, we sequenced the complete genome of C.

Acta Veterinaria Scandinavica, 2011 Background In Gram-negative bacteria, the most commonly studied quorum sensing signals are the N-acylhomoserine lactones (AHLs). In Salmonella, AHLs are recognized by SdiA, which is believed to be a sensor of AHLs produced by other bacteria, since ...

SdiA, an N-acylhomoserine lactone receptor, becomes active during the transit of Salmonella enterica through the gastrointestinal tract of turtles. [PDF]
PLoS One, 2008 Background LuxR-type transcription factors are typically used by bacteria to determine the population density of their own species by detecting N-acylhomoserine lactones (AHLs).

A second N-acylhomoserine lactone signal produced by Pseudomonas aeruginosa. [PDF]
Proceedings of the National Academy of Sciences, 1995 Quorum sensing systems are used by a number of Gram-negative bacterial species to regulate specific sets of genes in a cell density-dependent manner. Quorum sensing involves synthesis and detection of extracellular signals termed autoinducers. As shown in recombinant Escherichia coli, the Pseudomonas aeruginosa autoinducer (PAI) N-(3-oxododecanoyl ...

PfmA, a novel quorum-quenching N-acylhomoserine lactone acylase from Pseudoalteromonas flavipulchra.
Microbiology, 2017 Many bacteria, such as Proteobacteria, Cyanobacteria and Bacteroidetes, use N-acylhomoserine lactones (AHLs) as quorum-sensing (QS) signal molecules for communication. Enzymatic degradation of AHLs, such as AHL acylase and AHL lactonase, can degrade AHLs (quorum quenching, QQ) to attenuate or disarm the virulence of pathogens.

Journal of microorganism control, 2023 Many gram-negative pathogens can activate virulence factors under the control of N-acylhomoserine lactone (AHL）-mediated quorum sensing. AHL-degrading enzymes have been investigated for their application in disease control.

The growth characteristics of algae in the presence of N-acylhomoserine lactones
Water Supply, 2023 Abstract Algal–bacterial symbiotic system is ubiquitous in natural water and has an important impact on water quality and environment such as algal toxins from extracellular secretions. In general, the species diversity and abundance of this system can be dynamically regulated by quorum sensing (QS).
