Structural insights into acyl-ACP selective recognition by the Aeromonas hydrophila AHL synthase AhyI [PDF]
BMC Microbiology, 2021 Background Aeromonas hydrophila is a gram-negative bacterium and the major causative agent of the fish disease motile aeromonad septicemia (MAS). It uses N-acyl-homoserine lactone (AHL) quorum sensing signals to coordinate biofilm formation, motility ...

Hypersensitive Response of Plasmid-Encoded AHL Synthase Gene to Lifestyle and Nutrient by Ensifer adhaerens X097 [PDF]
Frontiers in Microbiology, 2017 It is known that some bacteria, especially members of the family Rhizobiaceae, have multiple N-acyl homoserine lactones (AHL) synthase genes and produce multiple AHL signals.

Stenotrophomonas maltophilia responds to exogenous AHL signals through the LuxR solo SmoR (Smlt1839) [PDF]
Frontiers in Cellular and Infection Microbiology, 2015 Quorum Sensing (QS) mediated by Acyl Homoserine Lactone (AHL) molecules are probably the most widespread and studied among Gram-negative bacteria. Canonical AHL systems are composed by a synthase (LuxI family) and a regulator element (LuxR family), whose

Phenotypic and genotypic characterisation of Burkholderia cenocepacia J2315 mutants affected in homoserine lactone and diffusible signal factor-based quorum sensing systems suggests interplay between both types of systems. [PDF]
PLoS ONE, 2013 Many putative virulence factors of Burkholderia cenocepacia are controlled by various quorum sensing (QS) circuits. These QS systems either use N-acyl homoserine lactones (AHL) or cis-2-dodecenoic acid ("Burkholderia diffusible signal factor", BDSF) as ...

The plant growth-promoting Burkholderia vietnamiensis produces acyl-homoserine lactones and modulates the quorum-sensing signaling in the rhizosphere [PDF]
Frontiers in MicrobiologyThe genus Burkholderia, comprising over 60 species, represents a highly diverse group of bacteria known for their exceptional metabolic versatility. Quorum sensing (QS), a mechanism of cell-density-dependent gene regulation, plays a critical role in host

A covariation analysis reveals elements of selectivity in quorum sensing systems
eLife, 2021 Many bacteria communicate with kin and coordinate group behaviors through a form of cell-cell signaling called acyl-homoserine lactone (AHL) quorum sensing (QS). In these systems, a signal synthase produces an AHL to which its paired receptor selectively

Identification of a solo acylhomoserine lactone synthase from the myxobacterium Archangium gephyra
Scientific Reports, 2021 Considered a key taxon in soil and marine microbial communities, myxobacteria exist as coordinated swarms that utilize a combination of lytic enzymes and specialized metabolites to facilitate predation of microbes.
