Siderophores: More than Stealing Iron [PDF]

mBio, 2016
Siderophores are small molecular iron chelators that are produced by microbes and whose most notable function is to sequester iron from the host and provide this essential metal nutrient to microbes.

Cyanobacterial Siderophores—Physiology, Structure, Biosynthesis, and Applications [PDF]

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.

Bacillus anthracis Siderophores [PDF]

Проблемы особо опасных инфекций, 2016
Iron is an essential for growth and reproduction of bacteria element. One of the ways of its acquisition by Bacillus anthracis is utilization of high-affinity chelating agents of iron ions - bacillibactin and petrobactin siderophores, extracting the iron

Pseudomonas siderophores: production, spectrophotometry detection and Botrytis suppression [PDF]

Notulae Scientia Biologicae
Siderophores are iron-chelating agents produced by almost all microorganisms in response to iron deficiency. Due to the requirement of iron for cell growth and metabolism, siderophore-mediated acquisition of iron plays a central role in determining the ...

EFFECT OF SIDEROPHORES AGAINST E. COLI O157:H7 [PDF]

Italian Journal of Food Safety, 2012
In this study, the inhibiting activity of siderophores produced by Pseudomonas fluorescens against Escherichia coli O157:7 was assayed. Siderophores were extracted from P. fluorescens cultures and preliminarily tested by C.A.S. reagent and UV.

Development and application of an assay for uranyl complexation by fungal metabolites, including siderophores [PDF]

, 2003
An assay to detect UO2 2+ complexation was developed based on the chrome azurol S (CAS) assay for siderophores (B. Schwyn and J. B. Neilands, Anal. Biochem.

Fungal siderophores : structures, functions and applications

, 2002
Siderophores are low molecular weight, iron-chelating ligands produced by nearly all microorganisms. Fungi synthesize a wide range of hydroxamate siderophores.

Structural and Functional Siderophore Remodeling by Enzymatic Delipidation. [PDF]

Angew Chem Int Ed Engl
A 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 ...

Novel strains of Bacillus cereus Wah1 and Enterobacter cloacae Wkh with high potential for production of siderophores [PDF]

Biological Journal of Microorganism, 2017
Introduction: Siderophores are relatively low-weight molecules (500 to 1000 Dalton), which are produced by many microorganisms as the chelating ligands of iron under iron deficiency.
