Distribution of siderophore gene systems on a Vibrionaceae phylogeny: Database searches, phylogenetic analyses and evolutionary perspectives. [PDF]
PLoS ONE, 2018 Siderophores are small molecules synthesized and secreted by bacteria and fungi to scavenge iron. Extracellular ferri-siderohores are recognized by cognate receptors on the cell surface for transport over membranes.

Gram-positive siderophore-shuttle with iron-exchange from Fe-siderophore to apo-siderophore by Bacillus cereus YxeB [PDF]
Proceedings of the National Academy of Sciences, 2013 Small molecule iron-chelators, siderophores, are very important in facilitating the acquisition of Fe(III), an essential element for pathogenic bacteria. Many Gram-negative outer-membrane transporters and Gram-positive lipoprotein siderophore-binding proteins have been characterized, and the binding ability of outer-membrane transporters ...

The design and synthesis of an antibacterial phenothiazine–siderophore conjugate
Beilstein Journal of Organic Chemistry, 2018 Siderophore–antibiotic conjugates consist of an antibiotic covalently linked by a tether to a siderophore. Such conjugates can demonstrate enhanced uptake and internalisation to the bacterial cell resulting in significantly reduced MIC values and ...

The Siderophore Metabolome of Azotobacter vinelandii [PDF]
Applied and Environmental Microbiology, 2016 ABSTRACT In this study, we performed a detailed characterization of the siderophore metabolome, or “chelome,” of the agriculturally important and widely studied model organism Azotobacter vinelandii . Using a new high-resolution liquid chromatography-mass spectrometry (LC-MS) approach, we found over 35 ...

Recent advances in siderophore biosynthesis
Current Opinion in Chemical Biology, 2009 The biosynthesis of the microbial small molecule iron scavengers known as siderophores has been of interest since their discovery in the middle of the past century. Two main pathways for siderophore biosynthesis exist. One is directed by a large family of modular multienzymes called non-ribosomal peptide synthetases (NRPSs) while the other is NRPS ...

Siderophore-Mediated Mobilization of Manganese Limits Iron Solubility in Mixed Mineral Systems [PDF]
, 2023 Recent laboratory and field studies show the need to consider the formation of aqueous Mn(III)-siderophore complexes in manganese (Mn) and iron (Fe) geochemical cycling, a shift from the historical view that aqueous Mn(III) species are unstable and thus ...

Production of siderophore type chelates by mixed bacterioplankton populations in nutrient enriched seawater incubations [PDF]
, 2004 Siderophore type chelates were isolated from nutrient enriched seawater collected from coastal and near shore environments and detected using a novel high performance liquid chromatography – electrospray ionisation – mass spectrometric technique ...

Siderophore-like molecules facilitate enhanced iron uptake.
, 2023 Cultures of DSS3 cells that were grown in either low or high-iron media were able to acquire iron more effectively when supplemented with SLMs than cultures of DSS3 cells that were not supplemented with SLMs.
