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

Formation of the Chromophore of the Pyoverdine Siderophores by an Oxidative Cascade
Organic Letters, 2003The pyoverdine chromophore is formed in a reaction involving a two-electron oxidation, a conjugate addition, and a second two-electron oxidation. This oxidative cascade can be carried out with polyphenol oxidase (PPO), MnO(2), and cell-free extracts from Pseudomonas aeruginosa. [reaction: see text]

From Pseudomonas sp. CFML 96.188 a pyoverdine was isolated and its primary structure was elucidated by spectroscopic methods and degradation reactions. This strain is of interest as it accepts the structurally different pyoverdines from several other Pseudomonas strains.

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 ...

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.

From a genetically manipulated strain of Pseudomonas aeruginosa ATCC 15692 (PAO1 strain) a compound named pseudoverdin, 3-formylamino-6,7-dihydroxycoumarin, was obtained which is related to the typical pyoverdin chromophore and thus allows to shed some light on the biogenesis of the latter.

From Pseudomonas chlororaphis D-TR 133 a pyoverdine was isolated and its primary structure were elucidated by spectroscopic methods and degradation reactions. Despite some structural differences, its Fe(III) complex and that of the pyoverdine from Pseudomonas fluorescens CHA0 were taken up by either strain with a high rate.
