Identification of QuiP, the Product of Gene PA1032, as the Second Acyl-Homoserine Lactone Acylase of Pseudomonas aeruginosa PAO1 [PDF]

open access: yes, 2006
The relevance of the acyl homoserine lactone (acyl-HSL) quorum signals N-3-oxododecanoyl-homoserine lactone (3OC12HSL) and N-butanoyl-homoserine lactone to the biology and virulence of Pseudomonas aeruginosa is well investigated.

One‐Step and Universal Strategy for the Synthesis of Hypermodified Uracil Phosphoramidites acp3U and cmnm5U

open access: yesChemistry – A European Journal, Volume 32, Issue 16, 25 April 2026.
One‐step, highly efficient, and scalable synthesis of acp3U phosphoramidite is described, as well as a new alternative synthesis of cmnm5U phosphoramidite from a highly versatile intermediate. Latter could be scaled‐up, split, and aliquots turned simultaneously into cmnm5U, nm5U, and mnm5U.

Metabolic engineering strategies for L-Homoserine production in Escherichia coli

open access: yesMicrobial Cell Factories
L-Homoserine, serves as a non-essential precursor for the essential amino acids derived from L-aspartate in both animals and humans. It finds widespread applications across the food, cosmetics, pharmaceutical, and animal feed industries.

An Unprecedented Medium-Chain Diunsaturated N-acylhomoserine Lactone from Marine Roseobacter Group Bacteria

open access: yesMarine Drugs, 2018
N-acylhomoserine lactones (AHLs), bacterial signaling compounds involved in quorum-sensing, are a structurally diverse group of compounds. We describe here the identification, synthesis, occurrence and biological activity of a new AHL, N-((2E,5Z)-2,5 ...

Engineering New‐to‐Nature Biological Pathways for β,γ‐Alkanediol Synthesis

open access: yesAdvanced Science, Volume 13, Issue 23, 23 April 2026.
β,γ‐Alkanediols are value‐added chemicals to be used as functional solvents, biofuels, and cosmetic components. This work demonstrates a carboligation‐mediated approach for synthesis of linear chain β,γ‐alkanediols in Escherichia coli, namely, hexane‐2,3‐diol (2,3‐HDO) and pentane‐2,3‐diol (2,3‐PDO). The engineered E. coli cells produce 152.2 mm (17.98

Evaluation of a new high-throughput method for identifying quorum quenching bacteria [PDF]

open access: yes, 2013
Quorum sensing (QS) is a population-dependent mechanism for bacteria to synchronize social behaviors such as secretion of virulence factors. The enzymatic interruption of QS, termed quorum quenching (QQ), has been suggested as a promising alternative ...

Pinus nigra and Pinus brutia Extracts Inhibit Quorum Sensing in Pseudomonas aeruginosa PAO1 with Minimal Impact on Fibroblast Cell Viability and Calcium Deposition

open access: yesFood Science &Nutrition, Volume 14, Issue 4, April 2026.
Extracts of Pinus nigra and Pinus brutia inhibit quorum sensing in Pseudomonas aeruginosa PAO1 by reducing pyocyanin and elastase production. This effect is associated with the downregulation of QS‐related genes, including lasR, lasI, rhlI, and rhlR. Additionally, the extracts exhibit minimal, dose‐ and time‐dependent effects on the metabolic activity ...

Rhodotorula Mucilaginosa, a Quorum Quenching Yeast Exhibiting Lactonase Activity Isolated from a Tropical Shoreline

open access: yesSensors, 2014
Two microbial isolates from a Malaysian shoreline were found to be capable of degrading N-acylhomoserine lactones. Both Matrix Assisted Laser Desorption Ionization-Time of Flight-Mass Spectrometry and 18S rDNA phylogenetic analyses confirmed that these ...
