LuxR Solos From Environmental Fluorescent Pseudomonads.
MSphere, 2021 LuxR solos are related to quorum sensing (QS) LuxR family regulators; however, they lack a cognate LuxI family protein. LuxR solos are widespread and almost exclusively found in proteobacteria.

Census of Solo LuxR Genes in Prokaryotic Genomes [PDF]
Frontiers in Cellular and Infection Microbiology, 2015 luxR genes encode transcriptional regulators that control acyl homoserine lactone-based quorum sensing (AHL QS) in Gram negative bacteria. On the bacterial chromosome, luxR genes are usually found next or near to a luxI gene encoding the AHL signal ...

LuxR Solos in Photorhabdus Species [PDF]
Frontiers in Cellular and Infection Microbiology, 2014 Bacteria communicate via small diffusible molecules to mediate group-coordinated behavior, a process designated as quorum sensing. The basic molecular quorum sensing system of Gram-negative bacteria consists of a LuxI-type autoinducer synthase producing ...

MSystems, 2023 Many proteobacteria possess LuxR solos which are quorum sensing LuxR-type regulators that are not paired with a cognate LuxI-type synthase. LuxR solos have been implicated in intraspecies, interspecies, and interkingdom communication by sensing ...

Expanding the LuxR-type receptor functional repertoire: Protein-protein interactions in quorum sensing regulation. [PDF]
PLoS PathogensQuorum sensing (QS) enables bacteria to coordinate gene expression in response to population density, with LuxR-type transcription factors playing a central role in this process for many Gram-negative species. Traditionally understood as ligand-activated

Frontiers in Cellular and Infection Microbiology, 2015 LuxR solo transcriptional regulators contain both an autoinducer binding domain (ABD; N-terminal) and a DNA binding Helix-Turn-Helix domain (HTH; C-terminal), but are not associated with a cognate N-acyl homoserine lactone (AHL) synthase coding gene in ...

Frontiers in Microbiology, 2020 LuxR solos are common in plant-associated bacteria and increasingly recognized for playing important roles in plant-microbe interkingdom signaling. Unlike the LuxR-type transcriptional regulators of prototype LuxR/LuxI quorum sensing systems, luxR solos ...

Stenotrophomonas maltophilia Responds to Exogenous AHL Signals Through the LuxR Solo SmoR (Smlt1839)
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

Frontiers in Molecular Biosciences, 2021 LuxR, a bacterial quorum sensing-related transcription factor that responds to the signaling molecule 3-oxo-hexanoyl-homoserine lactone (3OC6-HSL). In this study, we employed molecular dynamics simulation and the Molecular Mechanics Generalized Born ...

Interactions among quorum sensing inhibitors. [PDF]
PLoS ONE, 2013 Many pathogenic bacteria use quorum sensing (QS) systems to regulate the expression of virulence genes in a density-dependent manner. In one widespread QS paradigm the enzyme LuxI generates a small diffusible molecule of the acyl-homoserine lactone (AHL)
