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).

Molecular Mechanisms of Plant Growth–Promoting Rhizobacteria (PGPR) in Biofertilization and Disease Suppression of Crops

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Plant growth–promoting rhizobacteria (PGPR) are beneficial soil bacteria that colonize the rhizosphere and enhance plant growth through direct and indirect mechanisms, including nutrient solubilization, phytohormone production, suppression of phytopathogens, and activation of plant defense mechanisms.

Peptide Arginases from Cryptic Pathways Install Ornithine Residues in Uncharacterized Members of Orphan RiPP Families

ChemBioChem, Volume 26, Issue 24, December 11, 2025.
The incorporation of the non‐proteinogenic amino acid ornithine into antibiotic peptides has shown potential in influencing antibacterial efficacy. Novel peptide arginases from cryptic ribosomally synthesized and post‐translationally modified peptide (RiPP) pathways are identified and found to incorporate ornithine residues into various peptide ...

Biosynthesis of H2S and Siderophores Targeting Gram‐Negative Bacterial Resistance to Reactive Oxygen Species

Advanced Science, Volume 12, Issue 45, December 4, 2025.
Discover how Gram‐negative bacteria develop resistance to reactive oxygen species, and how scientists aim to overcome this challenge. Abstract Reactive oxygen species (ROS) are a promising alternative bactericide. However, it is questioned that bacteria can potentially develop resistance to ROS, similar to their resistance against antibiotics and ...

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).

A New Pyoverdin from Pseudomonas aeruginosa R'

Zeitschrift für Naturforschung C, 2001
Abstract From a Pseudom onas aeruginosa hospital isolate a new pyoverdin was isolated. It is iden­tical with that of Pseudomonas aeruginosa strain R except that in the peptide chain L-Gln is missing.
