Targeting Agrobacterium tumefaciens: A Computational Study on Quorum Sensing Inhibition

Journal of Basic Microbiology, Volume 65, Issue 7, July 2025.
ABSTRACT Crown gall disease, caused by Agrobacterium tumefaciens, results in significant loss in agricultural productivity losses due to induced tumor‐like growths on various crops. The virulence of A. tumefaciens is controlled by its quorum sensing (QS) system, specifically through the TraR protein, which regulates the expression of genes essential ...

Cyclobutanone Inhibitor of Cobalt-Functionalized Metallo-γ-Lactonase AiiA with Cyclobutanone Ring Opening in the Active Site [PDF]

, 2021
An α-amido cyclobutanone possessing a C10 hydrocarbon tail was designed as a potential transition-state mimetic for the quorum-quenching metallo-γ-lactonase autoinducer inactivator A (AiiA) with the support of in-house modeling techniques and found to be

Quorum Sensing: A Prospective Therapeutic Target for Bacterial Diseases

BioMed Research International, Volume 2019, Issue 1, 2019., 2019
Bacterial quorum sensing (QS) is a cell‐to‐cell communication in which specific signals are activated to coordinate pathogenic behaviors and help bacteria acclimatize to the disadvantages. The QS signals in the bacteria mainly consist of acyl‐homoserine lactone, autoinducing peptide, and autoinducer‐2. QS signaling activation and biofilm formation lead

Dinuclear Gallium(III) Complex With 1,3‐Propanediamine‐N,N′‐Diacetate: Structural Characterization, Antimicrobial Activity, and DNA/BSA Interactions

Bioinorganic Chemistry and Applications, Volume 2025, Issue 1, 2025.
In this study, a tetradentate 1,3‐propanediamine‐N,N′-diacetate (1,3‐pdda2−) was utilized for the synthesis of a dinuclear gallium(III) complex, uns‐cis‐[Ga(1,3‐pdda)(µ‐OH)]2.2H2O (1). Complex 1 was characterized using IR and NMR (1H and 13C) spectroscopy, and its crystal structure was determined by single‐crystal X‐ray diffraction analysis.

Dual control of hydrogen cyanide biosynthesis by the global activator GacA in Pseudomonas aeruginosa PAO1 [PDF]

, 2017
The global response regulator GacA of Pseudomonas aeruginosa PAO1 positively controls the production of the quorum sensing signal molecule N-butanoyl-homoserine-lactone (C4-HSL) and hence the synthesis of several C4-HSL-dependent virulence factors ...

CerM and Its Antagonist CerN Are New Components of the Quorum Sensing System in Cereibacter sphaeroides, Signaling to the CckA/ChpT/CtrA System

MicrobiologyOpen, Volume 13, Issue 6, December 2024.
The quorum sensing (QS) system of Cereibacter sphaeroides includes six LuxR homologs and one acylhomoserine lactone synthase homolog. Two LuxR homologs, CerM and CerN, are involved in regulating the expression of ctrA, which is part of the CckA/ChpT/CtrA two‐component system that controls flagellar motility.
