Molecular mechanisms of N‐acyl homoserine lactone signals perception by plants
Cell Biology International, 2021AbstractN‐acyl homoserine lactones (AHLs) belong to the class of bacterial quorum sensing signal molecules involved in distance signal transduction between Gram‐negative bacteria colonizers of the rhizosphere, as well as bacteria and plants. AHLs synchronize the activity of genes from individual cells, allowing the bacterial population to act as a ...

Solution structural features of N -acyl homoserine lactones
Tetrahedron Letters, 2015Here we demonstrate that in interbacterial quorum signal moderators, N-acylhomoserine lactones (AHLs), the stabilization of bioactive pharmacophore lactone against lysis is through the e(-) withdrawing N-acyl motif which reduces lactone carbonyl polarization. This lysis is assisted by weak (

Acyl-Homoserine Lactone Biosynthesis: Structure and Mechanism
2014The first quorum-sensing system to be discovered was the Lux system of Vibrio fischeri, which regulates light production in the light organ of deep sea fish and squid via an acyl-homoserine lactone (AHL) signaling molecule. The LuxI-type AHL synthases catalyze the formation of the AHL from the substrates S-adenosyl-L-methionine (SAM) and acyl-acyl ...

Self perception in bacteria: quorum sensing with acylated homoserine lactones
Current Opinion in Microbiology, 1998A variety of Gram-negative bacteria produce membrane permeant, acylated homoserine lactone (HL) pheromones that act as cell density cues. Synthesis and response to these factors requires proteins homologous to the Luxl acylhomoserine lactone synthase and the LuxR transcription factor from Vibrio fischeri.

PA-I lectin from Pseudomonas aeruginosa binds acyl homoserine lactones
Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2005The study analyses the binding affinities of Pseudomonas aeruginosa PA-I lectin (PA-IL) to three N-acyl homoserine lactones (AHSL), quorum sensing signal molecules responsible for cell-cell communication in bacteria. It shows that like some plant lectins, PA-IL has a dual function and, besides its carbohydrate-binding capacity, can accommodate AHLS ...

Acylated Homoserine Lactone Signaling in Marine Bacterial Systems
2014This chapter reviews the current understanding of acylated homoserine lactone (AHL) signaling in marine bacterial systems outside of the well-described Vibrio fischeriand Vibrio harveyi models. AHL production has far only been documented in proteobacterial groups.

Applied Microbiology and Biotechnology, 2014
The cell-to-cell communication of microorganisms is known to be via exertion of certain chemical compounds (signal molecules) and is referred to as quorum sensing (QS). QS phenomenon is widespread in microbial communities. Several Gram-positive and Gram-negative bacteria and fungi use lactone-containing compounds (e.g.

LacZ‐Based Detection of Acyl‐Homoserine Lactone Quorum‐Sensing Signals
Current Protocols in Microbiology, 2006AbstractMany bacteria use quorum‐sensing regulatory systems to monitor their population density and to coordinate their genetic expression under certain conditions. Acyl‐homoserine lactones are often produced by many Gram‐negative bacteria and serve as quorum‐sensing signal molecules.

Modeling the effect of acylated homoserine lactone antagonists in Pseudomonas aeruginosa
Biosystems, 2005Pseudomonas aeruginosa is a gram-negative bacterium that causes serious illnesses, particularly in immunocompromised individuals, often with a fatal outcome. The finding that the acylated homoserine lactone quorum sensing (QS) system controls the production of virulence factors in P.
