Biofilms, homoserine lactones and biocide susceptibility [PDF]

open access: yesJournal of Antimicrobial Chemotherapy, 2004
To investigate the susceptibility, to a range of different biocides, of Pseudomonas aeruginosa strains variously deficient in N-acyl homoserine lactone systems, grown either as planktonic or biofilm populations.Biocide susceptibility data were generated for strains of P. aeruginosa deficient in N-acyl homoserine lactone production, grown planktonically

Characterization of Quorum Sensing and Quorum Quenching Soil Bacteria Isolated from Malaysian Tropical Montane Forest

open access: yesSensors, 2012
We report the production and degradation of quorum sensing N-acyl-homoserine lactones by bacteria isolated from Malaysian montane forest soil. Phylogenetic analysis indicated that these isolates clustered closely to the genera of Arthrobacter, Bacillus ...

Long Chain N-acyl Homoserine Lactone Production by Enterobacter sp. Isolated from Human Tongue Surfaces

open access: yesSensors, 2012
We report the isolation of N-acyl homoserine lactone-producing Enterobacter sp. isolate T1-1 from the posterior dorsal surfaces of the tongue of a healthy individual. Spent supernatants extract from Enterobacter sp.

Unusual Multiple Production of N-Acylhomoserine Lactones a by Burkholderia sp. Strain C10B Isolated from Dentine Caries

open access: yesSensors, 2014
Bacteria realize the ability to communicate by production of quorum sensing (QS) molecules called autoinducers, which regulate the physiological activities in their ecological niches.

Homoserine Toxicity in Saccharomyces cerevisiae and Candida albicans Homoserine Kinase ( thr1 Δ) Mutants [PDF]

open access: yesEukaryotic Cell, 2010
ABSTRACT In addition to threonine auxotrophy, mutation of the Saccharomyces cerevisiae threonine biosynthetic genes THR1 (encoding homoserine kinase) and THR4 (encoding threonine synthase) results in a plethora of other phenotypes.

Involvement of Acylated Homoserine Lactones (AHLs) of Aeromonas sobria in Spoilage of Refrigerated Turbot (Scophthalmus maximus L.)

open access: yesSensors, 2016
One quorum sensing strain was isolated from spoiled turbot. The species was determined by 16S rRNA gene analysis and classical tests, named Aeromonas sobria AS7.

Potential of a Quorum Quenching Bacteria Isolate Ochrobactrum intermedium D-2 Against Soft Rot Pathogen Pectobacterium carotovorum subsp. carotovorum

open access: yesFrontiers in Microbiology, 2020
Quorum quenching (QQ) is a promising strategy for preventing and controlling quorum sensing (QS)-mediated bacterial infections. It interferes with QS by the inhibition of signal synthesis, the detection of enzyme-catalyzed degradation, and the ...

Quorum Sensing Activity in Pandoraea pnomenusa RB38

open access: yesSensors, 2014
Strain RB38 was recovered from a former dumping area in Malaysia. MALDI-TOF mass spectrometry and genomic analysis identified strain RB-38 as Pandoraea pnomenusa. Various biosensors confirmed its quorum sensing properties.

Methionine and threonine synthesis are limited by homoserine availability and not the activity of homoserine kinase in Arabidopsis thaliana [PDF]

open access: yesThe Plant Journal, 2005
SummaryHomoserine kinase (HSK) produces O‐phospho‐l‐homoserine (HserP) used by cystathionine γ‐synthase (CGS) for Met synthesis and threonine synthase (TS) for Thr synthesis. The effects of overexpressing Arabidopsis thaliana HSK, CGS, and Escherichia coli TS (eTS), each controlled by the 35S promoter, were compared.

Cofactor engineering for improved production of 2,4-dihydroxybutyric acid via the synthetic homoserine pathway

open access: yesFrontiers in Bioengineering and Biotechnology
(L)-2,4-dihydroxybutyrate (DHB) is a versatile compound that can serve as a precursor for the synthesis of the methionine analog 2-hydroxy-4-(methylthio)butyrate and new advanced polymers.
