Structural and Functional Siderophore Remodeling by Enzymatic Delipidation. [PDF]
Angew Chem Int Ed EnglA surprising functional switch in bacterial siderophores was discovered through genome mining and the analysis of environmental and pathogenic Pandoraea species. Pandorachelin B, a lipocyclopeptide that promotes swarming motility, is cleaved by a specialized acylase, yielding a ring‐contracted, homodetic cyclopeptide, pandorachelin A, which exhibits ...

Mise en évidence de l’impact des sidérophores dans l’immunité des plantes et évaluation du potentiel clinique des conjugués antibiotiques-sidérophores [PDF]
, 2020 Les bactéries peuvent être à la fois nos amies et nos ennemies. Nos amies parce qu’elles nous assistent de plusieurs manières : par exemple dans la digestion de nourritures ainsi que dans le renforcement de notre système immunitaire.

Cyanobacterial Siderophores—Physiology, Structure, Biosynthesis, and Applications
Marine Drugs, 2019 Siderophores are low-molecular-weight metal chelators that function in microbial iron uptake. As iron limits primary productivity in many environments, siderophores are of great ecological importance.

Biosynthesis Pathways, Transport Mechanisms and Biotechnological Applications of Fungal Siderophores
Journal of Fungi, 2021 Iron (Fe) is the fourth most abundant element on earth and represents an essential nutrient for life. As a fundamental mineral element for cell growth and development, iron is available for uptake as ferric ions, which are usually oxidized into complex ...
