Total Synthesis of Pyoverdin D
Pyoverdin D is an important siderophore that is used by the human pathogen Pseudomonas aeruginosa to import iron and gain a competitive advantage. This unique partially cyclic octapeptide bears four nonproteinogenic amino acids, including (δ)N-formyl-(δ)N-hydroxy-l-ornithine, and a catechol containing chiral chromophore. Here, we report the first total

Siderophore activity of pyoverdin for Pseudomonas aeruginosa [PDF]
Pseudomonas aeruginosa produces an extracellular compound with yellowish green fluorescence, called pyoverdin, which functions as a siderophore. The production of pyoverdin, formerly called fluorescein, is concomitant with the production of another siderophore, pyochelin. Pyoverdin is produced by P.

Iron Acquisition from Fe-Pyoverdine by Arabidopsis thaliana
Taking into account the strong iron competition in the rhizosphere and the high affinity of pyoverdines for Fe(III), these molecules are expected to interfere with the iron nutrition of plants, as they do with rhizospheric microbes.

Characterization of pyoverdine and achromobactin in
Background Pseudomonas syringae pv. phaseolicola 1448a (P. syringae 1448a), the causative agent of bean halo blight, is a bacterium capable of occupying diverse biological niches. Under conditions of iron starvation P.

Cell aggregation promotes pyoverdine-dependent iron uptake and virulence in Pseudomonas aeruginosa
In Pseudomonas aeruginosa the Gac signaling system and the second messenger cyclic diguanylate (c-di-GMP) participate in the control of the switch between planktonic and biofilm lifestyles, by regulating the production of the two exopolysaccharides Pel ...

The Pyoverdins of Pseudomonas syringae and Pseudomonas cichorii
Abstract The structure elucidation of the cyclic (lactonic) forms of the pyoverdins with a succinamide side chain originally produced by the closely related species Pseudomonas syringae and P. cichorii is reported. Mass spectrometry and nuclear magnetic resonance analyses as well as the determination of the configuration of the amino ...

Pyoverdin is essential for virulence of Pseudomonas aeruginosa [PDF]
The role of pyoverdin, the main siderophore in iron-gathering capacity produced by Pseudomonas aeruginosa, in bacterial growth in vivo is controversial, although iron is important for virulence. To determine the ability of pyoverdin to compete for iron with the human iron-binding protein transferrin, wild-type P. aeruginosa ATCC 15692 (PAO1 strain) and

Synopsis. The [68Ga]GaIII‐TREN‐CAM radiochelate selectively accumulates in Gram‐negative sites of infection and noninvasively monitors treatment response a siderophore antibiotic. ABSTRACT Positron emission tomography (PET) is an emerging tool under clinical investigation for the detection of bacterial infections.

Pyoverdine, the Major Siderophore in Pseudomonas aeruginosa, Evades NGAL Recognition
Pseudomonas aeruginosa is the most common pathogen that persists in the cystic fibrosis lungs. Bacteria such as P. aeruginosa secrete siderophores (iron-chelating molecules) and the host limits bacterial growth by producing neutrophil-gelatinase ...
