The biosynthesis of pyoverdines [PDF]

open access: yesMicrobial Cell, 2018
Pyoverdines are fluorescent siderophores of pseudomonads that play important roles for growth under iron-limiting conditions. The production of pyoverdines by fluorescent pseudomonads permits their colonization of hosts ranging from humans to plants.

Periodically Disturbing the Spatial Structure of Biofilms Can Affect the Production of an Essential Virulence Factor in Pseudomonas aeruginosa

open access: yesmSystems, 2021
Understanding the environmental factors that affect the production of virulence factors has major implications in evolution and medicine. While spatial structure is important in virulence factor production, observations of this relationship have occurred

Pyoverdine aus Pseudomonas putida / Pyoverdins from Pseudomonas putida

open access: yesZeitschrift für Naturforschung C, 1992
The structures of two pyoverdins (Pp 1 and Pp 2) and one dihydropyoverdin (dihydro-Pp 2) from a strain of Pseudomonas putida have been elucidated by spectroscopic methods and degradation studies. The pyoverdins Pp 1 and Pp2 consist of a chromophore which was identified as (1 S)-5-amino-2,3-dihydro-8,9-dihydroxy-1 H-pyrimido[1,2-a]quinoline-1-carboxylic

Rapid development of cefiderocol resistance in a carbapenem-resistant Pseudomonas aeruginosa isolate associated with mutations in the pyoverdine biosynthesis pathway

open access: yesJournal of Global Antimicrobial Resistance, 2023
: Here we report the in vivo development of cefiderocol resistance within 11 days after therapy initiation in a critically ill patient with bloodstream infection, infection of peri-anal fistula, and pneumonia caused by a VIM-2 harbouring, carbapenem ...

The RND efflux system ParXY affects siderophore secretion in Pseudomonas putida KT2440

open access: yesMicrobiology Spectrum, 2023
Tripartite efflux systems transport antimicrobial agents, toxic metabolites, and siderophores from Gram-negative cells into the environment. For example, the main siderophore pyoverdine of the soil bacterium Pseudomonas putida KT2440 is secreted into the

Total Synthesis of Pyoverdin D

open access: yesOrganic Letters, 2013
Pyoverdin D is an important siderophore that is used by the human pathogen Pseudomonas aeruginosa to import iron and gain a competitive advantage. This unique partially cyclic octapeptide bears four nonproteinogenic amino acids, including (δ)N-formyl-(δ)N-hydroxy-l-ornithine, and a catechol containing chiral chromophore. Here, we report the first total

Siderophore activity of pyoverdin for Pseudomonas aeruginosa [PDF]

open access: yesInfection and Immunity, 1985
Pseudomonas aeruginosa produces an extracellular compound with yellowish green fluorescence, called pyoverdin, which functions as a siderophore. The production of pyoverdin, formerly called fluorescein, is concomitant with the production of another siderophore, pyochelin. Pyoverdin is produced by P.

The Pyoverdins of Pseudomonas syringae and Pseudomonas cichorii

open access: yesZeitschrift für Naturforschung C, 2004
Abstract The structure elucidation of the cyclic (lactonic) forms of the pyoverdins with a succinamide side chain originally produced by the closely related species Pseudomonas syringae and P. cichorii is reported. Mass spectrometry and nuclear magnetic resonance analyses as well as the determination of the configuration of the amino ...
