Droperidol as a Potential Inhibitor of Acyl-homoserine Lactone Synthase from A. baumannii: Insights from Virtual Screening, MD Simulations and MM/PBSA Calculations [PDF]
, 2022 A. baumannii belongs to the ESKAPE family of pathogens and is a multi-drug resistant, gram-negative bacteria which follows the anaerobic form of respiration. A. baumannii is known to be the causative agent of hospital-related infections such as pneumonia,

Microorganisms, 2020 Quorum sensing (QS) is a cell density-dependent mechanism that regulates the expression of specific genes in microbial cells. Quorum quenching (QQ) is a promising strategy for attenuating pathogenicity by interfering with the QS system of pathogens.

Enzymatic Assays to Investigate Acyl-Homoserine Lactone Autoinducer Synthases. [PDF]
Methods Mol Biol, 2018 Bacteria use chemical molecules called autoinducers as votes to poll their numerical strength in a colony. This polling mechanism, commonly referred to as quorum sensing, enables bacteria to build a social network and provide a collective response for fighting off common threats.

Regulation of acylated homoserine lactones (AHLs) in beef by spice marination [PDF]
Journal of Food Science and Technology, 2016 Quorum sensing (QS) is a signaling mechanism used by bacteria to communicate each other through the release of auto-inducing signaling molecules. Despite the fact that bacteria regulate its phenotypes by QS mechanism, their potential role in meat spoilage is not yet elucidated.

Acyl homoserine lactone-based quorum sensing in a methanogenic archaeon [PDF]
The ISME Journal, 2012 Abstract Acyl homoserine lactone (AHL)-based quorum sensing commonly refers to cell density-dependent regulatory mechanisms found in bacteria. However, beyond bacteria, this cell-to-cell communication mechanism is poorly understood. Here we show that a methanogenic archaeon, Methanosaeta harundinacea 6Ac, encodes an active quorum sensing

A novel metagenomic short-chain dehydrogenase/reductase attenuates Pseudomonas aeruginosa biofilm formation and virulence on Caenorhabditis elegans. [PDF]
PLoS ONE, 2011 In Pseudomonas aeruginosa, the expression of a number of virulence factors, as well as biofilm formation, are controlled by quorum sensing (QS). N-Acylhomoserine lactones (AHLs) are an important class of signaling molecules involved in bacterial QS and ...

Specificity of Acyl-Homoserine Lactone Synthases Examined by Mass Spectrometry [PDF]
Journal of Bacteriology, 2006 ABSTRACT Many gram-negative bacteria produce a specific set of N -acyl- l -homoserine-lactone (AHL) signaling molecules for the purpose of quorum sensing, which is a means of regulating coordinated gene expression in a cell-density-dependent manner.
