Noise and kinetics of LuxR positive feedback loops

Biochemical and Biophysical Research Communications, 2007
We have previously reported the design and construction of positive feedback loops (PFLs) based on the LuxI-LuxR quorum-sensing system that can be used as modular transcriptional regulatory units for the construction of complex artificial genetic circuits.

Characterization of a LuxR repressor for 3,17β-HSD in Comamonas testosteroni ATCC11996

Chemico-Biological Interactions, 2021
3,17β-Hydroxysteroid dehydrogenase in Comamonas testosteroni (C. testosteroni) is a key enzyme involved in the degradation of steroid compounds. Recently, we found that LuxR is a negative regulator in the expression of the 3,17β-HSD gene. In the present work, we cultured wild-type and LuxR knock-out mutants of C.

Roles of LuxR-family regulators in the biosynthesis of secondary metabolites in Actinobacteria

World Journal of Microbiology and Biotechnology, 2022
Actinobacteria are well-known Gram-positive bacteria that produce approximately two-thirds of microbial bioactive natural products (NPs) through secondary metabolism. Usually, genes involved in the biosynthesis of NPs in actinobacteria are clustered, and their expression is regulated by an elaborate and stringent regulatory network formed by diverse ...

Quorum Sensing and LuxR Solos in Photorhabdus

2016
Bacterial communication via small diffusible molecules to mediate group-coordinated behaviour is commonly referred to as 'quorum sensing'. The prototypical quorum sensing system of Gram-negative bacteria consists of a LuxI-type autoinducer synthase that produces acyl-homoserine lactones (AHLs) as signals and a LuxR-type receptor that detects the AHLs ...

Role and regulation of bacterial LuxR-like regulators

Journal of Cellular Biochemistry, 2011
LuxR transcriptional regulator is a key player in Quorum Sensing (QS), coordinates the expression of a variety of genes, including those encoding virulence factors and antibiotics biosynthesis, motility, nodulation, plasmid transfer, bioluminescence, and biofilm formation. The characteristics and roles of this family, especially those of Mycobacterium,

The LuxR regulator protein controls synthesis of polyhydroxybutyrate in Vibrio harveyi

BBA - Proteins and Proteomics, 1998
The LuxR regulatory protein of Vibrio harveyi has been shown to control synthesis of polyhydroxybutyrate (PHB) as well as luminescence so as to occur at high cell density, suggesting that it is a general regulatory protein. Mutants defective in the production of LuxR (D1, D34, and MR1130) were found to be missing PHB, whose synthesis could be restored ...
