Structure-Function Analyses of the N-Butanoyl l-Homoserine Lactone Quorum-Sensing Signal Define Features Critical to Activity in RhlR.

ACS Chemical Biology, 2018
Pseudomonas aeruginosa is an opportunistic pathogen that coordinates the production of many virulence phenotypes at high population density via quorum sensing (QS). The LuxR-type receptor RhlR plays an important role in the P.

Microbial regulation of global macroalgal blooms (green tides): From holobiont interactions to bloom dynamics and biogeochemistry

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Green tides caused by Ulva species have become one of the most serious marine ecological disasters, now impacting many coastal nations around the world. Although climatic and environmental drivers of these macroalgal blooms are well recognized, growing evidence identifies Ulva‐associated microbiota as potential pivotal regulators of bloom ...

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

Structural analysis of mycobacterial homoserine transacetylases central to methionine biosynthesis reveals druggable active site

Scientific Reports, 2019
Mycobacterium tuberculosis is the cause of the world’s most deadly infectious disease. Efforts are underway to target the methionine biosynthesis pathway, as it is not part of the host metabolism.

The Factors Involved in Plant–Insect–Microbe Interactions Expanded: Genome Analysis and Description of Frigoribacterium adelgis sp. nov.

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Aerobic Actinobacteria belonging to the genus Frigoribacterium were isolated from adelgid Adelges (Aphrastasia) pectinatae collected from a Korean fir tree. Genomic analysis showed that these bacteria encode a range of factors that may be involved in the interactions between Frigoribacterium strains, adelgids and/or Korean fir trees.

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.

The synthesis of an analogue of the locust CRF-like diuretic peptide, and the biological activities of this and some C-terminal fragments. [PDF]

, 2003
The synthesis is described of an analogue of the locust CRF-like diuretic peptide in which methionine in positions 1,3, and 13 is replaced by isosteric methyl-homoserine residues.

Porin‐Independent Uptake of Small Molecule Antibiotics Facilitated by Escherichia coli Outer Membrane Vesicles

Biotechnology and Bioengineering, Volume 123, Issue 1, Page 235-244, January 2026.
We demonstrate that bacterial outer membrane vesicles (OMVs) can enhance antibiotic delivery into Gram‐negative bacteria by bypassing porin‐dependent uptake. Encapsulation of imipenem in OMVs significantly increased its effectiveness against multidrug‐resistant clinical isolates, highlighting OMVs as a promising platform for overcoming permeability ...

A Sinorhizobium meliloti-specific N-acyl homoserine lactone quorum-sensing signal increases nodule numbers in Medicago truncatula independent of autoregulation

Frontiers in Plant Science, 2014
N-acyl homoserine lactones (AHLs) act as quorum sensing signals that regulate cell-density dependent behaviors in many gram-negative bacteria, in particular those important for plant-microbe interactions.

Conformational changes in the catalytic region are responsible for heat-induced activation of hyperthermophilic homoserine dehydrogenase

Communications Biology, 2022
Heat-induced maturation of homoserine dehydrogenase from a hyperthermophilic archaeon requires conformational changes within the catalytic region.
