Requires Mg2+. Aerobactin is one of a group of high-affinity iron chelators known as siderophores and is produced under conditions of iron deprivation . It is a dihydroxamate comprising two molecules of N6-acetyl-N6-hydroxy-L-lysine and one molecule of citric acid. This enzyme catalyses the second of two synthase reactions to link N6-acetyl-N6-hydroxy-L-lysine and citrate [3,4,5].
