Siderophores are low molecular weight, high-affinity iron(III) ligands, produced by bacteria to solubilize and promote iron
uptake under low iron conditions. Two prominent structural features characterize the majority of the marine siderophores discovered
so far: (1) a predominance of suites of amphiphilic siderophores composed of an iron(III)-binding headgroup that is appended
by one or two of a series of fatty acids and (2) a prevalence of siderophores that contain α-hydroxycarboxylic acid moieties
(e.g., β-hydroxyaspartic acid or citric acid) which are photoreactive when coordinated to Fe(III). Variation of the fatty
acid chain length affects the relative amphiphilicity within a suite of siderophores. Catecholate sulfonation is another structural
variation that would affect the hydrophilicity of a siderophore. In addition to a review of the marine amphiphilic siderophores,
we report the production of petrobactin disulfonate by Marinobacter aquaeolei VT8.
