Precursor activation in a pyoverdine biosynthesis
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1990The 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 ...

Fluorescent complex of pyoverdin with aluminum
Journal of Inorganic Biochemistry, 2003When 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.

Structure of the Pyoverdin PVD 2908 – a new Pyoverdin from Pseudomonas sp. 2908
Biometals, 1999An 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, 2022The 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
2014Siderophores 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.

Chemistry and Biology of Pyoverdines, Pseudomonas Primary Siderophores
Current Medicinal Chemistry, 2014Pyoverdine is the generic name given to a vast family of fluorescent green-yellowish pigments produced by Pseudomonas species. Pseudomonas aeruginosa is an opportunistic pathogen, particularly infecting humans with compromised natural defenses. These infections result in significantly higher morbidity, longer hospitalization, increased mortality rates ...

Pyoverdine siderophores: from biogenesis to biosignificance
Trends in Microbiology, 2007Pyoverdines 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, 1994The 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.
