Quorum Sensing Activity of Serratia fonticola Strain RB-25 Isolated from an Ex-landfill Site

Sensors, 2014
Quorum sensing is a unique bacterial communication system which permits bacteria to synchronize their behaviour in accordance with the population density.

Positive Autoregulation of an Acyl-Homoserine Lactone Quorum-Sensing Circuit Synchronizes the Population Response

mBio, 2017
Many proteobacteria utilize acyl-homoserine lactone quorum-sensing signals. At low population densities, cells produce a basal level of signal, and when sufficient signal has accumulated in the surrounding environment, it binds to its receptor, and ...

Identification and measurement of homoserine by gas-liquid chromatography

Analytical Biochemistry, 1980
Abstract Homoserine has been analyzed quantitatively by gas-liquid chromatography of its N-heptafluorobutyryl isopropyl ester. The method was confirmed by analysis of the soluble amino acid fraction of pea leaves. The possible use of the method for analysis of methionine is discussed.

The RhlR quorum-sensing receptor controls Pseudomonas aeruginosa pathogenesis and biofilm development independently of its canonical homoserine lactone autoinducer.

PLoS Pathogens, 2017
Quorum sensing (QS) is a bacterial cell-to-cell communication process that relies on the production, release, and response to extracellular signaling molecules called autoinducers.

The GCR1 and GPA1 Participate in Promotion of Arabidopsis Primary Root Elongation Induced by N-Acyl-Homoserine Lactones, the Bacterial Quorum-Sensing Signals

Molecular Plant-Microbe Interactions, 2012
Many gram-negative bacteria use N-acyl-homoserine lactones (AHL) as quorum-sensing signals to coordinate their collective behaviors. Accumulating evidence indicates that plants can respond to AHL. However, little is known about the molecular mechanism of

Effect of the luxI/R gene on AHL-signaling molecules and QS regulatory mechanism in Hafnia alvei H4

AMB Express, 2019
Hafnia alvei H4 is a bacterium subject to regulation by a N-acyl-l-homoserine lactone (AHL)-mediated quorum sensing system and is closely related to the corruption of instant sea cucumber.

Unravelling the genome of long chain N-acylhomoserine lactone-producing Acinetobacter sp. strain GG2 and identification of its quorum sensing synthase gene

Frontiers in Microbiology, 2015
Myriad proteobacteria use N-acyl homoserine lactone (AHL) molecules as quorum-sensing (QS) signals to regulate different physiological functions, including virulence, antibiotic production and biofilm formation.

Biofunctionalization of Silver Nanoparticles With Lactonase Leads to Altered Antimicrobial and Cytotoxic Properties

Frontiers in Molecular Biosciences, 2019
Background: N-acylated homoserine lactone lactonase which cleave the Acyl homoserine lactone molecules produced by biofilm-forming pathogens and silver nano-particles (AgNPs), are known for their antibacterial effect against several Gram-positive and ...

l-Homoserine Fermentation

Agricultural and Biological Chemistry, 1961
In the course of studies on “negative feedback control” mechanisms caused by threonine and methionine in l-homoserine fermentation with Micrococcus glutamicus 534-Co147 culture, l-homoserine dehydrogenase was first found to occur in the culture, and effects of various amino acids on the formation and action of the enzyme were then investigated.
