RpoE binds directly to the luxR promoter region. [PDF]
, 2016 (A) EMSAs were performed with purified RpoE, and the luxR promoter region was analyzed. The amount of RpoE protein (nM) that was used is indicated, and 20 ng of each Cy5-labelled probe was added to the EMSA reactions.

LuxR-family ‘solos’: bachelor sensors/regulators of signalling molecules [PDF]
Microbiology, 2009 N-Acylhomoserine lactone (AHL) quorum-sensing (QS) signalling is the best-understood chemical language in proteobacteria. In the last 15 years a large amount of research in several bacterial species has revealed in detail the genetic, molecular and biochemical mechanisms underlying AHL signalling. These studies have revealed the role

Global H-NS counter-silencing by LuxR activates quorum sensing gene expression [PDF]
, 2019 Bacteria coordinate cellular behaviors using a cell–cell communication system termed quorum sensing. In Vibrio harveyi, the master quorum sensing transcription factor LuxR directly regulates >100 genes in response to changes in population density.

Robust and sensitive control of a quorum‐sensing circuit by two interlocked feedback loops
Molecular Systems Biology, 2008 The quorum‐sensing (QS) response of Vibrio fischeri involves a rapid switch between low and high induction states of the lux operon over a narrow concentration range of the autoinducer (AI) 3‐oxo‐hexanoyl‐L‐homoserine lactone.

Frontiers in Microbiology, 2019 The most common quorum sensing (QS) system in Gram-negative bacteria consists of signaling molecules called N-acyl-homoserine lactones (AHLs), which are synthesized by an enzyme AHL synthase (LuxI) and detected by a transcriptional regulator (LuxR) that ...

The LuxR receptor: the sites of interaction with quorum-sensing signals and inhibitors [PDF]
Microbiology, 2005 The function of LuxR homologues as quorum sensors is mediated by the binding of N-acyl-l-homoserine lactone (AHL) signal molecules to the N-terminal receptor site of the proteins. In this study, site-directed mutagenesis was carried out of the amino acid residues comprising the receptor site of LuxR from Vibrio fischeri, and the ability of the L42A ...

Transcriptional Control during Quorum Sensing by LuxR and LuxR Homologues [PDF]
, 2003 Quorum sensing is a mechanism used by many proteobacteria to regulate expression of target genes in a population-dependent manner. The quorum sensing system of Vibrio fischeri activates the luminescence (lux) operon when the autoinducer signaling ...
