Allgemeine Beschreibung

N-(3-Oxooctanoyl)-L-homoserine lactone is a common quorum sensing (QS) signal.
It is a signaling molecule that is produced by Gram negative bacteria.

Anwendung

N-(3-Oxooctanoyl)-L-homoserine lactone has been used:
  • to study the effects of pH, temperature, and salinity on extracellular polymeric substances (EPS) of Pseudomonas aeruginosa biofilm.
  • as an AHL inducer to activate the quorum sensing pathways in Synechococcus elongatus.

Biochem./physiol. Wirkung

N-(3-Oxooctanoyl)-L-homoserine lactone stimulates the tra gene expression. It is an autoinducer and potent antagonist.

TraR is an Agrobacterium tumefaciens transcriptional regulator which binds the pheromone N-3-oxooctanoyl-L-homoserine lactone (AAI) in response to the bacterial population density. The TraR-AAI complex dimerizes and interacts with a specific 18-base-pair DNA sequence (TraBox), activating promoters containing this site. TraR

The quorum sensing system allows bacteria to sense their cell density and initiate an altered pattern of gene expression after a sufficient quorum of cells has accumulated. In Agrobacterium tumefaciens, quorum sensing controls conjugal transfer of the tumour- inducing plasmid

Many proteobacteria are able to monitor their population densities through the release of pheromones known as N-acylhomoserine lactones. At high population densities, these pheromones elicit diverse responses that include bioluminescence, biofilm formation, production of antimicrobials, DNA exchange, pathogenesis and symbiosis.

Conjugal transfer of Agrobacterium tumefaciens Ti plasmids is regulated by quorum sensing via the transcriptional activator TraR and the acyl-homoserine lactone Agrobacterium autoinducer (AAI). Unique to this system, the activity of TraR is negatively modulated by an antiactivator called TraM.
