Aerobactin is a bacterial iron chelating agent (siderophore)[1] found in E. coli.[2] It is a virulence factor enabling E. coli to sequester iron in iron-poor environments, for example, the urinary tract.[3]
Aerobactin is synthesised from the oxidation of lysine, as catalysed by the aerobactin synthase enzyme. The gene for this enzyme is found in the aerobactin operon, which is roughly 8 kilobases long and contains 5 or more genes in total.[4]
Yersinia pestis contains genes relating to aerobactin, but they have been inactivated by a frameshift mutation, thus Y. pestis is no longer able to synthesise aerobactin.[5]
