Pyoverdine Analysis - From High-resolution MS/MS Fragmentation to Ion Mobility Measurements.
Chimia (Basel), 2023 Microorganisms produce iron chelators called siderophores that are a rich source for drug discovery or plant protective agents. Pyoverdines are a class of siderophores from fluorescent Pseudomonas members and consist of different peptide chains specific ...

Siderophore activity of pyoverdin for Pseudomonas aeruginosa [PDF]
Infection and Immunity, 1985 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.

The RND efflux system ParXY affects siderophore secretion in Pseudomonas putida KT2440
Microbiology Spectrum, 2023 Tripartite efflux systems transport antimicrobial agents, toxic metabolites, and siderophores from Gram-negative cells into the environment. For example, the main siderophore pyoverdine of the soil bacterium Pseudomonas putida KT2440 is secreted into the

Novel Insights on Pyoverdine: From Biosynthesis to Biotechnological Application
International Journal of Molecular Sciences, 2022 Pyoverdines (PVDs) are a class of siderophores produced mostly by members of the genus Pseudomonas. Their primary function is to accumulate, mobilize, and transport iron necessary for cell metabolism.

Cell aggregation promotes pyoverdine-dependent iron uptake and virulence in Pseudomonas aeruginosa
Frontiers in Microbiology, 2015 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 ...

Induction of systemic resistance to Botrytis cinerea in tomato by Pseudomonas aeruginosa 7NSK2 : role of salicylic acid, pyochelin, and pyocyanin [PDF]
, 2002 The rhizobacterium Pseudomonas aeruginosa 7NSK2 produces secondary metabolites such as pyochelin (Pch), its precursor salicylic acid (SA), and the phenazine compound pyocyanin. Both 7NSK2 and mutant KMPCH (Pch-negative, SA-positive) induced resistance to

Pyoverdine, the Major Siderophore in Pseudomonas aeruginosa, Evades NGAL Recognition
Interdisciplinary Perspectives on Infectious Diseases, 2012 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 ...

Illuminating Siderophore Transporter Functionality with Thiopeptide Antibiotics
mBio, 2023 The Gram-negative opportunistic pathogen Pseudomonas aeruginosa is a leading cause of infections and mortality in immunocompromised patients. This organism can overcome iron deprivation during infection via the synthesis of two iron-chelating ...
