Pyoverdin is essential for virulence of Pseudomonas aeruginosa [PDF]

Infection and Immunity, 1996
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

A Complete Genome Resource and Bio-Control Activity of Soil-Isolated Pseudomonas citronellolis Strain M03 Against Onion-Pathogenic Burkholderia Species. [PDF]

Microbiologyopen
Pseudomonas citronellolis M03, isolated from field soil, was sequenced and its genome revealed ten biosynthetic clusters, including siderophore NRPS. Phenotypic assays showed strong antagonism against onion‐pathogenic Burkholderia spp., reducing B.

The Pyoverdins of Pseudomonas syringae and Pseudomonas cichorii

Zeitschrift für Naturforschung C, 2004
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 ...

Structural and Functional Siderophore Remodeling by Enzymatic Delipidation

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.
A surprising functional switch in bacterial siderophores was discovered through genome mining and the analysis of environmental and pathogenic Pandoraea species. Pandorachelin B, a lipocyclopeptide that promotes swarming motility, is cleaved by a specialized acylase, yielding a ring‐contracted, homodetic cyclopeptide, pandorachelin A, which exhibits ...

Identification and validation of a novel anti-virulent that binds to pyoverdine and inhibits its function

Virulence, 2020
Pseudomonas aeruginosa: causes serious infections in patients with compromised immune systems and exhibits resistance to multiple antibiotics. The rising threat of antimicrobial resistance means that new methods are necessary for treating microbial ...

Biogenesis of the Pyoverdin Chromophore

Zeitschrift für Naturforschung C, 1997
Abstract After growing Pseudomonas aeruginosa in the presence of 2 ,4-[4-15N]-diaminobutyric acid (Dab) its incorporation into the quinoline chromophore of the pyoverdin produced by this bacterium could be shown by mass and NMR-spectroscopic techniques.

Succinopyoverdins - a New Variety of the Pyoverdin Chromophore

Zeitschrift für Naturforschung C, 2000
Abstract Pseudomonas spp. of the fluorescent group produce siderophores (so-called pyoverdins) consisting of a peptide chain attached to a pyrimidoquinoline ring system which is derived from a condensation product of L-Dab and D-Tyr. Commonly several related compounds are found to accompany the pyoverdins having the same peptide chain ...
