The lungs of cystic fibrosis patients are frequently colonized by Pseudomonas aeruginosa, which produces high-affinity fluorescent peptidic siderophores, pyoverdines. Three pyoverdines which differ in their peptide chain and are easily differentiated by isoelectric focusing exist, only one being produced by a given strain. P.

Activation of 6-phosphogluconate dehydrase by pyoverdine
Biochemical and Biophysical Research Communications, 1968Abstract Pseudomonas mildenbergii , when grown without iron, produces a green fluorescent pigment, pyoverdine ( Love & Hulcher, 1964 ), which has a molecular weight of 2,380 and consists of a peptide of threonine, serine, glutamic acid and lysine (4:2:1:1, molar ratio) with an N-methyl phenylacetyl hydroxamic acid group bound to the peptide

Pyoverdine type siderophores from pseudonomas fluorescens
Tetrahedron, 1987Abstract The structure of pyoverdine I, II and III isolated from the culture medium of Pseudomonas fluoresaens have been elucidated by spectroscopic methods and degradation studies. The pyoverdines consist of a chromophore which could be identified as 5-amino-2,3-dihydro-8,9-dihydroxy-1H-pyrimido [l,2-a]quinoline-l-R-carboxy1ic acid substituted at ...

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 ...

Selective ciprofloxacin antibiotic detection by fluorescent siderophore pyoverdin
Biosensors and Bioelectronics, 2016Fluorescent siderophore pyoverdin (PVD) was produced from a soil isolate Pseudomonas monteilii strain MKP 213. The PVD was purified near to homogeneity and applied for the fluorescent chemosensing of various antibiotics in aqueous solution (pH=7.0).

Under iron-limiting conditions, Pseudomonas aeruginosa secretes a fluorescent siderophore called pyoverdin (PaA), which, after complexing iron, is transported back into the cells via its outer membrane receptor FpvA. The recent finding that all FpvA receptors on the bacterial cell surface are loaded with iron-free PaA under iron limiting conditions has

Genomics of pyoverdine-mediated iron uptake in pseudomonads
Trends in Microbiology, 2003Pyoverdines (PVDs) are complex siderophores produced by members of the fluorescent Pseudomonas. They comprise a dihydroxyquinoline fluorescent chromophore joined to a peptide of remarkably variable length and composition. In Pseudomonas aeruginosa, PVDs also function as signal molecules for the production of virulence factors. Genes responsible for the

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.
