Biosynthesis of a clickable pyoverdine via in vivo enzyme engineering of an adenylation domain

Microbial Cell Factories
The engineering of non ribosomal peptide synthetases (NRPS) for new substrate specificity is a potent strategy to incorporate non-canonical amino acids into peptide sequences, thereby creating peptide diversity and broadening applications.

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.

Investigation of different methods in siderophore measurement in indigenous Fluorescent Pseudomonads [PDF]

Biological Journal of Microorganism, 2017
Introduction:Fluorescent pseudomonads produced a variety of siderophores in which the pyoverdine type siderophore is the main one. These bacteria employ siderophores to increase availability of Iron for their own and plants consumption. Siderophores have

Fluorescent Pseudomonad Pyoverdines Bind and Oxidize Ferrous Ion [PDF]

Applied and Environmental Microbiology, 1998
ABSTRACT Major pyoverdines from Pseudomonas fluorescens 2-79 (Pf-B), P. aeruginosa ATCC 15692 (Pa-C), and P. putida ATCC 12633 (Pp-C) were examined by absorption and fluorescence spectroscopic techniques to investigate the interaction between ferrous ion and ...

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 ...

Pyoverdin is essential for virulence of Pseudomonas aeruginosa [PDF]

Infection and Immunity, 1996
The role of pyoverdin, the main siderophore in iron-gathering capacity produced by Pseudomonas aeruginosa, in bacterial growth in vivo is controversial, although iron is important for virulence. To determine the ability of pyoverdin to compete for iron with the human iron-binding protein transferrin, wild-type P. aeruginosa ATCC 15692 (PAO1 strain) and

Mining microbial genomes for new natural products and biosynthetic pathways [PDF]

, 2008
Analyses of microbial genome sequences have revealed numerous examples of ‘cryptic’ or ‘orphan’ biosynthetic gene clusters, with the potential to direct the production of novel, structurally complex natural products.
