Labrenzia sp. BM1: A Quorum Quenching Bacterium That Degrades N-acyl Homoserine Lactones via Lactonase Activity

Sensors, 2014
We report the degradation of quorum sensing N-acylhomoserine lactone molecules by a bacterium isolated from a Malaysian marine water sample. MALDI-TOF and phylogenetic analysis indicated this isolate BM1 clustered closely to Labrenzia sp.

Homoserine Lactones Influence the Reaction of Plants to Rhizobia [PDF]

International Journal of Molecular Sciences, 2013
Bacterial quorum sensing molecules not only grant the communication within bacterial communities, but also influence eukaryotic hosts. N-acyl-homoserine lactones (AHLs) produced by pathogenic or beneficial bacteria were shown to induce diverse reactions in animals and plants. In plants, the reaction to AHLs depends on the length of the lipid side chain.

An Update: Enzymatic Synthesis for Industrial Applications

Angewandte Chemie International Edition, EarlyView.
Biocatalysis has become a sustainable and cost‐competitive alternative to established chemical synthesis, enabling the enzyme‐based production of not only commodity chemicals but (non‐natural) amino acids, (rare) sugars, as well as synthetic nucleotides.

Novel Bifunctional Acylase from Actinoplanes utahensis: A Versatile Enzyme to Synthesize Antimicrobial Compounds and Use in Quorum Quenching Processes

Antibiotics, 2021
Many intercellular communication processes, known as quorum sensing (QS), are regulated by the autoinducers N-acyl-l-homoserine lactones (AHLs) in Gram-negative bacteria.

Synthetic Biology‐Based Engineering Living Therapeutics for Antimicrobial Application

Exploration, EarlyView.
This perspective highlights synthetic biology‐driven antibacterial strategies, focusing on three innovative approaches: engineered bacteriophages for precision bacterial targeting, reprogrammed microbes that detect quorum‐sensing signals or metabolites to release antimicrobials, and engineering mammalian cells that recognize pathogen‐associated ...

Targeting Agrobacterium tumefaciens: A Computational Study on Quorum Sensing Inhibition

Journal of Basic Microbiology, EarlyView.
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 ...
