To date, the best known communication between bacteria occurs via the N-acyl
homoserine lactone (AHL): The enzyme Luxl produces signals that are recognised by the LuxR receptor, at which point the bacteria develop certain properties and modulate their behaviour towards one another.
In Gram negative bacteria, the QS mediated pathogenesis occurs through N-acyl
homoserine lactone (AHL) signal dependent mechanism (Smith and Iglewski 2003).
For example, red algae secrete halogenated furanones and enones that act as antagonists of acylated
homoserine lactone signaling molecules present in biofilms.
A receptor protein from the LuxR family of transcriptional regulators, upon binding an acylated
homoserine lactone compound, interacts with the lux box, modulating the activity of the promoter.
Addition of
homoserine lactone to the medium containing the mutant biofilms resulted in biofilms similar to the wild type with respect to structure and thickness.
Plants secrete substances that mimic bacterial N-acyl
homoserine lactone signal activities and affect population density-dependent behaviors in associated bacteria.
aeruginosa use N-acylated
homoserine lactone (AHL) as signal molecules.
Instead, the bacteria conserve their resources by making other chemicals, called acylated
homoserine lactones, or AHLs, which cost much less energy to produce, Hmelo said.
While most bacteria use a class of small signaling molecules called acylated
homoserine lactones, or AHLs, to "talk," E.
Among the most common chemical "words" in the marine environment are modified amino acids called acylated
homoserine lactones, or AHLs.
In Gram negative bacteria, the main signaling molecules are acyl
homoserine lactones.
40) demonstrated the role of acyl
homoserine lactones (HSL) in biofilms of P.
