Negative regulation of violacein biosynthesis in Chromobacterium violaceum [PDF]

, 2017
In Chromobacteium violaceum, the purple pigment violacein is under positive regulation by the N-acylhomoserine lactone CviI/R quorum sensing system and negative regulation by an uncharacterized putative repressor.

Isolation and identification of N-acylhomoserin lactone degrading bacteria from potato rhizosphere

African Journal of Microbiology Research, 2011
In many Gram-negative bacteria, including a number of pathogens such asPectobacterium carotovorum, virulence factor production and many functions are linked to the quorum sensing (QS) systems that use diffusible N-acyl homoserine lactones (AHLs) as intercellular messenger molecules.

Degradation of Bacterial Quorum Sensing Signaling Molecules by the Microscopic Yeast Trichosporon loubieri Isolated from Tropical Wetland Waters

Sensors, 2013
Proteobacteria produce N-acylhomoserine lactones as signaling molecules, which will bind to their cognate receptor and activate quorum sensing-mediated phenotypes in a population-dependent manner.

Potato Plants Genetically Modified to Produce N-Acylhomoserine Lactones Increase Susceptibility to Soft Rot Erwiniae

Molecular Plant-Microbe Interactions, 2004
Many gram-negative bacteria employ N-acylhomoserine lactones (AHL) to regulate diverse physiological processes in concert with cell population density (quorum sensing [QS]).

Novel approaches to the treatment of Pseudomonas aeruginosa infections in cystic fibrosis [PDF]

, 2012
Pseudomonas aeruginosa chronically infects patients with cystic fibrosis and is associated with greater morbidity. There has been limited progress on the clinical development of new antibiotics with novel modes of action.

Diversity‐Oriented Synthesis and Antibiofilm Evaluation of Furan‐2‐Carboxamides

ChemMedChem, Volume 20, Issue 9, May 5, 2025.
Navigating through the chemical space of antibiofilm agents! Furan‐2‐carboxamides inhibit the production of this extracellular shield in Pseudomonas aeruginosa by modulating the linkers and substituents of the central core. The discovery offers a solution to the metabolically unstable antibiofilm agents based on furanones, leading to the design of more

AhlX, an N-acylhomoserine Lactonase with Unique Properties

Marine Drugs, 2019
N-Acylhomoserine lactonase degrades the lactone ring of N-acylhomoserine lactones (AHLs) and has been widely suggested as a promising candidate for use in bacterial disease control.

Quorum Sensing Regulates the Hydrolytic Enzyme Production and Community Composition of Heterotrophic Bacteria in Coastal Waters

Frontiers in Microbiology, 2021
Heterotrophic microbial communities play a central role in biogeochemical cycles in the ocean by degrading organic matter through the synthesis of extracellular hydrolytic enzymes.

Bacterial N-acylhomoserine lactone-induced apoptosis in breast carcinoma cells correlated with down-modulation of STAT3 [PDF]

Oncogene, 2004
Cell growth is promoted by mitogens and survival factors, which activate intracellular signalling pathways to control cell cycle progression and cellular integrity. Proliferation signals are transmitted through Ras and Rho family small G-proteins coupled to mitogen-activated protein kinase (MAPK) cascades, while survival signals are propagated by lipid-
