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).

Antagonistic activity and role of pyoverdine in the antagonism.

, 2014
A. Antagonistic activity of the P. putida W15Oct28 strain against Pseudomonas aeruginosa, Curtobacterium flaccumfaciens, and Pseudomonas syringae. The pyoverdine-negative pvdO 2C5 transposon mutant has lost its antagonism against P.

Pseudotetraivprolide aus Pseudomonas entomophila liefern Einblicke in die Biosynthese von Detoxin/Rimosamid‐ähnlichen Anti‐Antibiotika

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Pseudotetraivprolid ist ein neuer Akteur unter den Detoxin/Rimosamid‐ähnlichen Naturstoffen. Die Biosynthese erfordert FabD aus dem Primärstoffwechsel und einen PipDFG‐Komplex für die Acetylierung im letzten Schritt – wodurch schließlich die anti‐antibiotische Wirkung entsteht.

AfΔsidA is more sensitive towards PA14 or pure pyoverdine than its wildtype.

, 2019
A: Mixtures (25%) of freshly prepared AF13073, AfΔsidA, AF46645, AfΔsidC, AfΔsidF, or AfS77 supernatants were combined with pyoverdine [10 μM], and tested for effects on 10AF forming biofilm metabolism.

Impact of Copper on the Physiology and Transcriptome of Methylosinus Trichosporium OB3b Grown on Either Methane or Methanol

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Methylosinus trichosporium OB3b can grow on methanol in the absence but not presence of copper due: (1) overgeneration of reducing power from methanol oxidation; (2) formate accumulation leading to acidification of the growth medium and inactivation of formate dehydrogenase; and (3) lack of expression of potential oxidative stress defence genes ...

Subcellular localization of the pyoverdine biogenesis machinery of Pseudomonas aeruginosa: a membrane-associated "siderosome"

, 2013
The peptidic siderophore pyoverdine is the primary iron uptake system of fluorescent pseudomonads, and a virulence factor in the opportunistic pathogen Pseudomonas aeruginosa.

Advancing the Development of Pseudomonas protegens PBL3 Secretome as a Biopesticide to Control Bacterial Panicle Blight in Rice

Plant Pathology, Volume 75, Issue 1, January/February 2026.
Pseudomonas protegens PBL3 secretome was successfully scaled up and provided effective preventive control of Bacterial Panicle Blight at the rice panicle stage, supporting its potential use as a practical, biologically based management tool. ABSTRACT Bacterial panicle blight (BPB), caused by Burkholderia glumae, is an emerging disease in rice that ...

Enhanced Fluorescent Siderophore Biosynthesis and Loss of Phenazine-1-Carboxamide in Phenotypic Variant of Pseudomonas chlororaphis HT66

Frontiers in Microbiology, 2018
Pseudomonas chlororaphis HT66 is a plant-beneficial bacterium that exhibits wider antagonistic spectrum against a variety of plant pathogenic fungi due to its main secondary metabolite, i.e., phenazine-1-carboxamide (PCN).
