Enterobactin is a siderophore produced by Gram-negative bacteria and has an extremely high affinity for iron. During the process of Salmonella typhimurium infecting macrophages, Enterobactin can not only help bacteria uptake iron but also reduce the antibacterial activity of macrophages. In addition, Enterobactin is also involved in the oxidative stress response of Escherichia coli. Enterobactin can be hydrolyzed by Fes in the cell and exert antioxidant effects by scavenging free radicals.
Application:
Enterobactin has been used: as a positive control in tryptophan fluorescence quenching experiments as a reference standard in high performance liquid chromatography to quantify Kosakonia radicincitans culture medium siderophores in the crystallization reservoir to remove iron contamination in the medium and in Fe-enterbactin binding studies This preparation of enterobactin is not bound to iron and will bind to Fe3+ and Fe2+ in solution.
Biochem/physiol Actions:
Enterobactin is a catechol (a benzenediol, C6H4(OH)2) type iron siderophore produced in small quantities by Escherichia coli and related enteric bacteria when grown on iron deficient media. It is one of the most powerful ferric ion complexing agents known.
Iron mobilization and uptake by microbes is mediated by low molecular weight complexing agents named siderophores. Enterobactin is a catechol (a benzenediol, C6H4(OH)2) type siderophore produced in small quantities by Escherichia coli and related enteric bacteria when grown on iron deficient media, and is one of the most powerful ferric ion complexing agents known. Enterobactin is a very effective sequestering agent for iron, able to remove iron from proteins, insoluble iron complexes, and other siderophores. Studies of the chemistry, regulation, synthesis, recognition, and transport of enterobactin make it the best-understood siderophore.

| Description | This compound belongs to the class of organic compounds known as cyclic depsipeptides. These are natural or synthetic compounds having sequences of amino and hydroxy carboxylic acid residues (usually α-amino and α-hydroxy acids) connected in a ring. The residues are commonly but not necessarily regularly alternating. |
