Salmochelin S4 (Fe-free) 1 mg

Siderophores

Siderophores (Greek for iron carrier) are a group of about 200 iron (Fe3+) binding chelating compounds (oligopeptides) produced by bacteria, fungi and plant roots, secreted to the surrounding medium. Siderophores show a very high affinity to Fe3+ ions, which allows to overcome the very low availability of soluble Fe3+ ions.

Salmochelins are enterobactin-related compounds, which are C-glucosylated at the 5-position of a 2,3-dihydroxybenzoyl residue. IroB transfers 2 glucose residues to enterobactin to form cyclic salmochelin S4.
