Synthesis of isotope labelled and photoactivatable N-acyl-L-homoserine lactones - inter kingdom signalling molecules [PDF]

, 2013
N-Acyl-L-homoserine lactones (AHLs) are signalling molecules. They enable bacteria to communicate with their eukaryotic host cells via inter-kingdom signalling. Very little is known about a mechanisms of such a interaction. Therefore isotope labelled and

The Assimilation of γ-Butyrolactone in Agrobacterium tumefaciens C58 Interferes with the Accumulation of the N-Acyl-Homoserine Lactone Signal

Molecular Plant-Microbe Interactions, 2004
Agrobacterium tumefaciens C58 communicates using N-acyl-homoserine lactones (acyl-HSL) and contains two lactonase-encoding genes, attM and aiiB, the products of which are capable of inactivating the acyl-HSL signal. In A.

Quorum Sensing Activity of Aeromonas Caviae Strain YL12, A Bacterium Isolated from Compost

Sensors, 2014
Quorum sensing is a well-studied cell-to-cell communication method that involves a cell-density dependent regulation of genes expression mediated by signalling molecules. In this study, a bacterium isolated from a plant material compost pile was found to

N-Acyl-homoserine Lactones from Enterobacter sakazakii (Cronobacter spp.) and Their Degradation by Bacillus cereus Enzymes

, 2016
A chemical study of acyl-homoserine lactones (acyl-HSLs) produced by Enterobacter sakazakii resulted in the identification of three molecules: (S)-N-heptanoyl-HSL, (S)-N-dodecanoyl-HSL and (S)-N-tetradecanoyl-HSL. Mixed cultures of E.

Selectivity and Efficiency of Conductive Molecularly Imprinted Polymer (c-MIP) Based on 5-Phenyl-Dipyrromethane and 5-Phenol-Dipyrromethane for Quorum Sensing Precursors Detection

Chemosensors, 2017
Functional polymers that selectively recognize target compounds are developed by imprinting polymerization. In the present paper, two different dipyrromethanes, 5-phenol-dipyrromethane (5-pOH-DP) and 5-phenyl-dipyrromethane (5-ph-DP), are synthetized and

Microbial metabolism of quorum-sensing molecules acyl-homoserine lactones, γ-heptalactone and other lactones

, 2014
The cell-to-cell communication of microorganisms is known to be via exertion of certain chemical compounds (signal molecules) and is referred to as quorum sensing (QS). QS phenomenon is widespread in microbial communities.

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.

Autonomous Control of Gene Expression Using Endogenous Transcription Signals

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Autonomous cell‐based control of heterologous gene expression can simplify batch‐culture bioprocessing by eliminating external monitoring and extrinsic control of culture conditions. Existing approaches use auto‐induction media, synthetic cell‐cell communication systems, or application‐specific biosensors.

Languages and dialects: bacterial communication beyond homoserine lactones

, 2015
Gram-negative bacteria use N-acyl homoserine lactones (acyl-HSLs) for communication, predominantly mediated by LuxR-type receptors. Recent studies uncovered aryl-HSLs, alpha-pyrones and dialkylresorcinols as further chemical languages of Gram-negative ...

Structural and Functional Siderophore Remodeling by Enzymatic Delipidation

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.
A surprising functional switch in bacterial siderophores was discovered through genome mining and the analysis of environmental and pathogenic Pandoraea species. Pandorachelin B, a lipocyclopeptide that promotes swarming motility, is cleaved by a specialized acylase, yielding a ring‐contracted, homodetic cyclopeptide, pandorachelin A, which exhibits ...
