The Structure of the Pyoverdin from Pseudomonas fluorescens 1.3. Structural and Biological Relationships of Pyoverdins from Different Strains

Zeitschrift für Naturforschung C, 1999
Abstract The structure of the pyoverdin siderophore of Pseudomonas fluorescens 1.3 was elucidated by spectroscopic methods and chemical degradation. It shows structural similarities with the pyoverdins of several other strains. Whether mutual recognition occurs was investigated by growth tests.

Highly Sensitive Determination of Pyoverdine in Cloud Water by HPLC-Thermal Lens Spectrometry

, 2016
New method for pyoverdine and Fe(III)-pyoverdine detection was developed. Two isomers of pyoverdine and two isomers of Fe(III)-pyoverdine were separated isocraticaly on reversed-phase (RP)-C18 chromatograhic column and detected by DAD, FLD and TLS.

Role of PvdMNO in the biosynthesis of pyoverdine, a siderophore of Pseudomonas Aerugionsa PA01

, 2006
Pyoverdine is a fluorescent, ferric iron binding siderophore produced by all Pseudomonas strains and is characterized by three distinct structural parts: a conserved dihydroxyquinoline chromophore, an acyl chain and various peptide chains. Three putative

Feature sequence-based genome mining uncovers the hidden diversity of bacterial siderophore pathways

eLife
Microbial secondary metabolites are a rich source for pharmaceutical discoveries and play crucial ecological functions. While tools exist to identify secondary metabolite clusters in genomes, precise sequence-to-function mapping remains challenging ...

Environmental determinants of pyoverdine production, exploitation and competition in naturalPseudomonascommunities

, 2018
SummaryMany bacteria rely on the secretion of siderophores to scavenge iron from the environment. Laboratory studies revealed that abiotic and biotic factors together determine how much siderophores bacteria make, and whether siderophores can be ...

The impact of physical disturbance and biofilm robustness on cooperative pyoverdine production in Pseudomonas aeruginosa

, 2020
Pseudomonas aeruginosa is a biofilm forming, pathogenic bacteria that can cause infections in humans with compromised immune systems (e.g. transplant patients, HIV positive individuals), and in individuals with cystic fibrosis. P.

Synthesis, cytotoxicity, and pyoverdine production inhibitory activity of actinomycin lactam analogs

Pyoverdines are fluorescent siderophores and potential virulence factors produced by Pseudomonas bacteria. Actinomycin D has been reported to inhibit pyoverdine production; however, its strong cytotoxicity limits its use as a probe to elucidate ...
