Siderophore-Mediated Iron Uptake in Fluorescent Pseudomonas: Characterization of the Pyoverdine-Receptor Binding Site of Three Cross-Reacting Pyoverdines

Archives of Biochemistry and Biophysics, 2002
Two Pseudomonas fluorescens and one Pseudomonas aeruginosa strains, although producing structurally different pyoverdines, demonstrated highly efficient cross-reactions when tested for pyoverdine-mediated iron uptake. A ferripyoverdine receptor-deficient mutant of the P. aeruginosa strain was unable to use any of the three pyoverdines.

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 ...

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.

Selection and development of aptamers for pyoverdine

The FASEB Journal, 2022
The rhizosphere is a small region surrounding plant roots that is enriched in biochemicals from root exudates and populated with fungi, nematode, and bacteria. Interaction of rhizosphere organisms with plants is mainly promoted by exudates from the roots.

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.

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 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.

Siderotyping A Powerful Tool for the Characterization of Pyoverdines

Current Topics in Medicinal Chemistry, 2001
Tools for the identification of bacteria are of great importance especially for taxonomical and medical purposes. In the case of fluorescent pseudomonads a quick and unambiguous identification is possible by methods that are referred to as "siderotyping".
