Role of the LuxR solo, SdiA, in eavesdropping on foreign bacteria

FEMS Microbiology Reviews
Abstract Bacteria can cooperate by coordinating their gene expression through the production, release, and detection of small molecules, a phenomenon known as quorum sensing (QS). One type of QS commonly found in Gram-negative bacteria utilizes a LuxI-type enzyme to produce a signaling molecule of the N-acyl-homoserine lactone (AHL ...

Structure and schematic behaviour of the LuxR-repressible promoters. [PDF]

, 2015
A) Schematic representation of the working principle of the repressible promoters. In the blue and red boxes the two synthetic networks representing the constitutive LuxR expression cassette and the LuxR-regulated RFP expression cassette are shown ...

A genome‐integrated CRISPR/Cas12a system enables efficient genetic engineering in Xenorhabdus budapestensis XBD8

New Plant Protection, Volume 3, Issue 2, June 2026.
We developed a genome‐integrated CRISPR/Cas12a system for Xenorhabdus budapestensis XBD8, which enables precise deletion or replacement of DNA fragments ranging from 379 to 45,168 bp, with a success rate exceeding 90%. Application of this tool for the dynamic regulation of fabclavine‐8 biosynthesis resulted in a 1.90‐fold increase in production ...

LuxR Solos in the Plant Endophyte Kosakonia sp. Strain KO348

Applied and Environmental Microbiology, 2020
Cell-cell signaling in bacteria allows a synchronized and coordinated behavior of a microbial community. LuxR solos represent a subfamily of proteins in proteobacteria which most commonly detect and respond to signals produced exogenously by other microbes or eukaryotic hosts.

Analysis of LuxR Regulon Gene Expression during Quorum Sensing in Vibrio fischeri [PDF]

, 2007
The regulation of the lux operon (luxICDABEG) of Vibrio fischeri has been intensively studied as a model for quorum sensing in proteobacteria. Two-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis previously identified ...

A Burkholderia cenocepacia Orphan LuxR Homolog Is Involved in Quorum-Sensing Regulation [PDF]

Journal of Bacteriology, 2009
ABSTRACT Burkholderia cenocepacia utilizes quorum sensing to control gene expression, including the expression of genes involved in virulence. In addition to CepR and CciR, a third LuxR homolog, CepR2, was found to regulate gene expression and virulence factor production. All B.

Halogenated furanones inhibit quorum sensing through accelerated LuxR turnover [PDF]

, 2002
N-acyl-L-homoserine lactones (AHLs) are co-regulatory ligands required for control of the expression of genes encoding virulence traits in many Gram-negative bacterial species.

An Evolving Perspective on the Pseudomonas aeruginosa Orphan Quorum Sensing Regulator QscR

Frontiers in Cellular and Infection Microbiology, 2014
Many Proteobacteria govern responses to changes in cell density by using acyl-homoserine lactone (AHL) quorum-sensing (QS) signaling. Similar to the LuxI-LuxR system described in Vibrio fischeri, a minimal AHL QS circuit comprises a pair of genes, a luxI-

LuxR-dependent quorum sensing: Computer aided discovery of new inhibitors structurally unrelated to N-acylhomoserine lactones [PDF]

, 2010
International audienceA virtual screening, involving flexible docking sequences within the LuxR, TraR and LasR binding sites, was used as a structural binding sites similarity filter to specifically target conserved residues in the proteins of the LuxR ...

2-Substituted Aniline as a Simple Scaffold for LuxR-Regulated QS Modulation

Molecules, 2017
The ability of the 2-substituted aniline motif to serve as a scaffold for designing potential LuxR-regulated quorum sensing (QS) modulators has been investigated, using docking experiments and biological evaluation of a series of 15 specially synthesized
