Invasion of Serratia proteamaculans is regulated by the sprI gene encoding AHL synthase

Microbes and Infection, 2021
Quorum Sensing (QS) system regulates gene expression in response to a change in the density of the bacterial population. Facultative pathogen Serratia proteamaculans 94 has a LuxI/LuxR type QS system consisting of regulatory protein SprR and AHL synthase SprI. Invasive activity of these bacteria appears at the stationary growth phase corresponding to a

Identification of quorum sensing signal AHLs synthases in Candidatus Jettenia caeni and their roles in anammox activity

Chemosphere, 2019
Acyl-homoserine lactone (AHL)-based quorum sensing (QS) in the anaerobic ammonium oxidizing (anammox) consortia has attracted increasing attention. However, AHL synthase in anammox bacteria and the relationship between AHL synthetic genes and anammox activity are still not clear because anammox bacteria have not been isolated from the consortia.

AHLS ‐pred: a novel sequence‐based predictor of acyl‐homoserine‐lactone synthases using machine learning algorithms

Environmental Microbiology Reports, 2022
Summary Acyl‐homoserine‐lactones (AHLs), as the major quorum sensing (QS) signalling molecules in Gram‐negative bacteria, have shown great application potential in regulating biological nutrient removal process. The identification of AHLs synthases plays an essential role in in‐depth research on QS mechanisms and applications of ...

Crystallization ofPseudomonas aeruginosaAHL synthase LasI using β-turn crystal engineering

Acta Crystallographica Section D Biological Crystallography, 2004
In Gram-negative bacteria, intercellular communication and virulence regulation is mediated by the diffusible chemical signal acyl-homoserine-L-lactone (AHL). The AHL synthase enzymes produce a variety of AHLs from the substrates S-adenosyl-L-methionine and acyl-acyl carrier protein.

Functional analysis of three AHL autoinducer synthase genes in Mesorhizobium loti reveals the important role of quorum sensing in symbiotic nodulation

Canadian Journal of Microbiology, 2009
One of the most important signal transduction pathways in bacteria, quorum sensing, is involved in many regulatory circuits in rhizobia, especially in the control of communication between rhizobia and their plant hosts. In this study, we identified 3 autoinducer synthase genes — mrlI1, mrlI2, and mrlI3 — in Mesorhizobium loti NZP 2213.

Integrating molecular docking and molecular dynamics simulation studies of afzelechin as a potential inhibitor of acyl-homoserine lactones (AHLs) synthase

Afghanistan Journal of Basic Medical Science
Introduction: Misuse of antimicrobial agents and inadequate treatment methods lead to recurrent infections due to microorganism resistance, multi-drug resistance, and biofilm formation. Acyl-homoserine lactones propagate resistance and establish a stable microbial population.
