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.

Study of pyoverdine type and production by Pseudomonas aeruginosa isolated from cystic fibrosis patients: prevalence of type II pyoverdine isolates and accumulation of pyoverdine-negative mutations

Archives of Microbiology, 2001
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, 1968
Abstract 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, 1987
Abstract 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, 2014
Pyoverdine 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, 2016
Fluorescent 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).

Recycling of Pyoverdin on the FpvA Receptor after Ferric Pyoverdin Uptake and Dissociation in Pseudomonas aeruginosa

Biochemistry, 2002
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, 2003
Pyoverdines (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
