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).

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, 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

Exploring the sociobiology of pyoverdin-producing Pseudomonas.
Evolution; international journal of organic evolution, 2013The idea that bacteria are social is a popular concept with implications for understanding the ecology and evolution of microbes. The view arises predominately from reasoning regarding extracellular products, which, it has been argued, can be considered "public goods." Among the best studied is pyoverdin-a diffusible iron-chelating agent produced by ...

Neue Pyoverdin-Siderophore ausPseudomonas putida C
Journal f�r Praktische Chemie/Chemiker-Zeitung, 1993New Pyoverdin Siderophores from Pseudomonas putida C Four new pyoverdins (C 2A, C 2B, C 3A, C 3B) were isolated from cultures of Pseudomonas putida C. Their structures were elucidated by chemical and spectroscopic methods. The compounds consist of a chromophore – (1S)-5-amino-2,3-dihydro-8,9-dihydroxy-1H-pyrimido [1,2-a]quinoline-1-carboxylic ...

Enzymology of the periplasmic pyoverdine maturation
2018Iron is of prominent importance for most living organisms, involved in many central processes, such as respiration or photosynthesis. To circumvent iron limitation, many organisms have developed strategies to keep ferric iron soluble, for instance by production of siderophores, which are small high-affinity iron-chelators.

[Pyoverdin-type siderophores from Pseudomonas aeruginosa].
Zeitschrift fur Naturforschung. C, Journal of biosciences, 1986From Pseudomonas aeruginosa three siderophores belonging to the pyoverdine group have been isolated which differ only in the acid side chains bound to the quinoline chromophore.
