Chemistry and biology of siderophores
Natural Product Reports, 2010Siderophores are compounds produced by bacteria, fungi and graminaceous plants for scavenging iron from the environment. They are low-molecular-weight compounds (500-1500 daltons) possessing a high affinity for iron(III) (Kf > 1030), the biosynthesis of which is regulated by iron levels and the function of which is to supply iron to the cell.

Fungal Genetics and Biology, 2015
Efficient iron acquisition mechanisms are fundamental for microbial survival in the environment and for pathogen virulence within their hosts. M. robertsii produces two known iron-binding natural products: metachelins, which are used to scavenge extracellular iron, and ferricrocin, which is strictly intracellular.

Bacterial siderophores promote plant growth: Screening of catechol and hydroxamate siderophores
International Journal of Phytoremediation, 2017The aim of the study was to determine the quality and quantity of siderophores produced by bacteria isolated from plants' roots. The second aim was to determine the effect of siderophores on plants growth (Festuca rubra L. and Brassica napus L.). The study was carried out using bacteria isolated from roots of: Arabidopsis thaliana L., F.

Microbial siderophores: a mini review
Journal of Basic Microbiology, 2012AbstractIron is one of the major limiting factors and essential nutrients of microbial life. Since in nature it is not readily available in the preferred form, microorganisms produce small high affinity chelating molecules called siderophores for its acquisition. Microorganisms produce a wide variety of siderophores controlled at the molecular level by

Siderophore-dependent ferrichelatases
Iron is a crucial secondary metabolite for bacterial proliferation, but its bioavailability under infection conditions is limited by the low solubility of ferric ion and the host's ability to sequester iron by protein chelation. In these iron limiting conditions, bacteria produce and secrete low molecular weight ferric ion chelators, siderophores, to ...C E, Merrick +2 more

Siderophores in Fungal Physiology and Virulence
Annual Review of Phytopathology, 2008Maintaining the appropriate balance of iron between deficiency and toxicity requires fine-tuned control of systems for iron uptake and storage. Both among fungal species and within a single species, different systems for acquisition, storage, and regulation of iron are present.

Siderophores, defined as iron(III) specific transport compounds, are widely distributed in aerobic and facultative anaerobic microbial species. The list of microbes known to form siderophores includes various enteric bacteria; human, animal and plant pathogenic bacteria and fungi; soil microorganisms; Gram positive and negative species, blue green alga

This chapter attempts to illustrate the occurrence of siderophores within different bacterial genera and explains the relationship between environmental factors and the biological function of siderophores, which may be summarized under the term "ecology of siderophores".

Siderophore production by Salmonella typhi
Biochemical and Biophysical Research Communications, 1988This study was initiated to determine the mechanism of iron-uptake in Salmonella typhi. When stressed for iron, microorganisms produce siderophores to obtain the necessary nutrient. Generally two types of siderophores exist: the phenolate-type predominantly produced by bacteria and the hydroxamate-type commonly secreted by fungi.
