Aplicación
Pyoverdines from Pseudomonas fluorescens has been used :
- in tryptophan fluorescence quenching to determine its binding to neutrophil-gelatinase-associated lipocalin (NGAL)
- to detect pyoverdine diffusion surrounding siderophore-conjugated monobactam (MB-1)-resistant colonies in chelexed, dialyzed Mueller-Hinton broth (CDMHB)
- for synchronous fluorescence spectra of purified pyoverdine
Acciones bioquímicas o fisiológicas
Pyoverdines help in promoting plant growth by chelating iron and rendering it unavailable for plant pathogens. The ferri-pyoverdine complex acts as a signaling molecule inducing the production of secreted virulence factors in Pseudomonas aeruginosa.
Pyoverdines, also called pseuobactins and pyoverdins, are fluorescent siderophores that have high affinity for iron (1032 M-1), and are synthesized by fluorescent pseudomonads under iron-deficient growth conditions. Pyoverdines were shown to prevent iron toxicity produced by iron overload in hepatocyte cultures and effectively scavenges the hydroxyl and peroxyl radicals. Pyoverdines are effective in acquiring iron from transferrin and lactoferrin. Pyoverdines are also involved in the suppression of pythium-induced damping-off of tomato and promotion of growth in some higher plants.

During chronic cystic fibrosis (CF) infections, evolved Pseudomonas aeruginosa antibiotic resistance is linked to increased pulmonary exacerbations, decreased lung function, and hospitalizations. However, the virulence mechanisms underlying worse outcomes caused by antibiotic resistant infections are poorly understood. Here, we investigated
