Genes required for free phage production are essential for pseudomonas aeruginosa chronic lung infections [PDF]

, 2015
The opportunistic pathogen Pseudomonas aeruginosa causes chronic lung infection in patients with cystic fibrosis. The Liverpool Epidemic Strain LESB58 is highly resistant to antibiotics, transmissible, and associated with increased morbidity and ...

Ferribactins -the Biogenetic Precursors of Pyoverdins

Zeitschrift für Naturforschung C, 1991
Abstract From ferribactins which accompany pyoverdins in iron deficient cultures of fluorescent pseudomonads a subunit has been obtained formed by condensation of D-tyrosin with L-2,4-diaminobutyric acid to give 2-(1-R-amino-2-p-hydroxyphenylethyl)-1,4,5,6-tetrahydropyrimidine-4-S′-carboxylic acid (1).

Siderophore-mediated iron dissolution from nontronites is controlled by mineral cristallochemistry

Frontiers in Microbiology, 2016
Bacteria living in oxic environments experience iron deficiency due to limited solubility and slow dissolution kinetics of iron-bearing minerals. To cope with iron deprivation, aerobic bacteria have evolved various strategies, including release of ...

Feature sequence-based genome mining uncovers the hidden diversity of bacterial siderophore pathways

eLife
Microbial secondary metabolites are a rich source for pharmaceutical discoveries and play crucial ecological functions. While tools exist to identify secondary metabolite clusters in genomes, precise sequence-to-function mapping remains challenging ...

Efficient Synthesis of the Pyoverdine Chromophore: Expanding the Toolbox for the Preparation of Pyoverdine Conjugates

European Journal of Organic Chemistry
AbstractThe pyoverdine chromophore is an important component of a family of siderophores which are secreted by the human pathogen Pseudomonas aeruginosa for iron absorption. In this study, an efficient and improved synthetic route to the chromophore structure is reported, beginning from readily available starting materials, D‐glutamic acid and L–DOPA ...
