The phenazine pyocyanin is a terminal signalling factor in the quorum sensing network of Pseudomonas aeruginosa [PDF]

open access: yes, 2006
Certain members of the fluorescent pseudomonads produce and secrete phenazines. These heterocyclic, redox-active compounds are toxic to competing organisms, and the cause of these antibiotic effects has been the focus of intense research efforts.

The Curious Case of CysE: Diversity and Distribution of Serine Acetyltransferases in Bacteria

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Serine acetyltransferase (CysE) is a member of the left‐handed β‐helix family of acetyltransferases that catalyze the rate limiting step in de novo cysteine biosynthesis. There are two isoforms of CysE that differ in length, with the shorter isoform lacking approximately 76 amino acids at the N‐terminus of the protein from the serine ...

Studies on amino acid metabolism in Lathyrus sativus Biosynthesis of homoserine and O-oxalylhomoserine

open access: yesActa Societatis Botanicorum Poloniae, 2015
Examination of free amino acid pool in Lathyrus sativus showed a rapid increase of homoserine and O-oxalylhomoserine during germination. Isotopic experiments indicated that aspartic acid was an effective precursor of homoserine in Lathyrus sativus and ...

Pyoverdine and proteases affect the response of pseudomonas aeruginosa to gallium in human serum [PDF]

open access: yes, 2015
Gallium is an iron mimetic which has recently been repurposed as an antibacterial agent due to its capability to disrupt bacterial iron metabolism. In this study, the antibacterial activity of gallium nitrate [Ga(NO3)3] was investigated in complement ...

Homoserine and Threonine Peptide Assembly [PDF]

open access: yesSynlett, 2017
Drawing on our recent success with reagent-less peptide-bond formation through serine-based assembly reactions in organic solvent, their range has been expanded to threonine and homoserine (an aspartic acid precursor) in the N-terminal peptide. Amino acid scope available at the assembly C-terminus includes bulky residues not amenable to classical ...

Taxonomic and functional shifts in the microbiome of severely obese, prediabetic patients: Ketogenic diet versus energy‐matched standard diet

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
Abstract Aims Obesity and type 2 diabetes mellitus (T2DM) are among the leading global health challenges of the 21st century. While caloric restriction remains the cornerstone of weight loss interventions, ketogenic diets (KD), characterised by low carbohydrate and high fat intake, have been shown to improve metabolic health partly by modulating the ...

A host-specific diaminobutyrate aminotransferase contributes to symbiotic performance, homoserine metabolism, and competitiveness in the Rhizobium leguminosarum/Pisum sativum system

open access: yesFrontiers in Microbiology, 2023
Rhizobium leguminosarum bv. viciae (Rlv) UPM791 effectively nodulates pea and lentil, but bacteroids contain a number of proteins differentially expressed depending on the host.

Screening of Indonesia Medicinal Plants Producing Quorum Sensing Inhibitor [PDF]

open access: yes, 2011
Antibiotic resistance of bacteria lead to create different way in the pathogen bacteria handling such us inhibit their quorum sensing mechanism. The goal of this study is to search quorum sensing inhibitor of seven Indonesia medicinal plants.

Phytohormone-mediated interkingdom signaling shapes the outcome of rice-Xanthomonas oryzae pv. oryzae interactions [PDF]

open access: yes, 2015
Background: Small-molecule hormones are well known to play key roles in the plant immune signaling network that is activated upon pathogen perception. In contrast, little is known about whether phytohormones also directly influence microbial virulence ...

Synthesis and Biological Evaluation of Novel L-Homoserine Lactone Analogs as Quorum Sensing Inhibitors of Pseudomonas aeruginosa.

open access: yesChemical and pharmaceutical bulletin, 2019
In this study, we synthesized four series of novel L-homoserine lactone analogs and evaluated their in vitro quorum sensing (QS) inhibitory activity against two biomonitor strains, Chromobacterium violaceum CV026 and Pseudomonas aeruginosa PAO1.
