Structure of the siderophore triacetylfusarinine encapsulating iron(III) within a tris(hydroxamate) coordination sphere (color code: red = oxygen, gray = carbon, blue = nitrogen, dark blue = iron).[1]
Iron compounds secreted by microorganisms
Siderophores (Greek: "iron carrier") are small, high-affinity iron-chelating compounds that are secreted by microorganisms such as bacteria and fungi. They help the organism accumulate iron.[2][3][4][5] Although a widening range of siderophore functions is now being appreciated,[6] siderophores are among the strongest (highest affinity) Fe3+ binding agents known. Phytosiderophores are siderophores produced by plants.
