Structure of the Pyoverdin PVD 2908 – a new Pyoverdin from Pseudomonas sp. 2908

Biometals, 1999
An unknown siderophore (pyoverdin) was isolated from the strain Pseudomonas sp. 2908. The structure of the pyoverdin--called PVD 2908--was elucidated by spectroscopic methods and degradation studies. Some other siderophores were identified by LC/ESI-MS-screening based on the knowledge of PVD 2908.

Pyoverdine siderophores: from biogenesis to biosignificance

Trends in Microbiology, 2007
Pyoverdines are a group of structurally related siderophores produced by fluorescent Pseudomonas species. Recent genomic and biochemical data have shed new light on the complex molecular steps of pyoverdine biogenesis and explained the chemical diversity of these compounds.

Solution Structure of Pyoverdin GM-II

Biochemistry, 1994
The three-dimensional structure in solution of ferri-pyoverdin GM-II isolated from the culture medium of Pseudomonas fluorescens was determined by application of NMR methods to the Ga3+ analogue. Distance geometry calculations were performed with FILMAN using interproton distances and coupling constants as constraints.

Pyoverdine and Pyochelin Measurements

2014
Siderophores are small organic chelators (of molecular weight between 200 and 2,000 Da), having a very high affinity for iron (10(17)-10(43) M(-1)). They are synthesized by bacteria and secreted into their environment in order to get access to iron, an essential element for bacterial growth.

Fluorescent complex of pyoverdin with aluminum

Journal of Inorganic Biochemistry, 2003
When a pyoverdin (PV), (a siderophore) from Pseudomonas fluorescens, binds aluminum 1:1, its natural fluorescence almost doubles, whereas PV-Fe is non-fluorescent. Complex formation allows [Al] determination down to 1 mug/l. Fe(III) in the sample interferes with [Al] determination, but added after PV, improves the assay's performance.

Precursor activation in a pyoverdine biosynthesis

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1990
The siderophore produced by Azotobacter vinelandii strain UW belongs to a large family of peptidic siderophores collectively called pyoverdines. The biosynthesis of the peptidyl moiety of this siderophore was shown to involve activation of the constituent amino acids as their adenylates, as demonstrated by amino acid-dependent ATP-[32P]pyrophosphate ...

Ferrofluid effect on Pseudomonas pyoverdine

Journal of Magnetism and Magnetic Materials, 2005
Abstract The magnetic fluid effect on some pigmented pathogen germs has been investigated. The fluorescence of the pyoverdine pigment obtained from Pseudomonas aeruginosa strain, cultivated in the presence of different magnetic fluid concentrations, was enhanced by magnetic fluid concentrations of 0.0015–1 ml/l.
