Siderophore - Wikipedia
https://en.wikipedia.org/wiki/Siderophore
webSiderophores are usually classified by the ligands used to chelate the ferric iron. The major groups of siderophores include the catecholates (phenolates), hydroxamates and carboxylates (e.g. derivatives of citric acid). Citric acid can also act as a siderophore.

Siderophores: From natural roles to potential applications
https://pubmed.ncbi.nlm.nih.gov/30798803/
webSiderophores present complex chemistry that allows them to form the strongest iron-chelating complexes. Interest in this field is always up to date and new siderophores are found with new roles and applications. For example, siderophores participate to the mobilization of iron and other elements and are involved in virulence processes.

webSiderophore secretion is a necessary step in bacterial iron acquisition. Perhaps the best characterized siderophore secretion pathway is enterobactin in E. coli, which is a multi-step process. First, enterobactin is transported from the cytoplasm to the periplasm via EntS (MFS-class efflux pump).

webSiderophores are iron-chelating agents that are secreted by living organisms such as bacteria, fungi, yeasts, and plants. Siderophores have relatively low molecular weight and a high affinity for trivalent metal ions (Fe3 + ). These ions are insoluble and found primarily in oxygenated environments ( Neilands, 1995; Chu et al., 2010 ).
