Enterobactin (also known as Enterochelin) is a high affinity siderophore that acquires iron for microbial systems. It is primarily found in Gram-negative bacteria such as Escherichia coli and Salmonella typhimurium.Enterobactin is the strongest siderophore known binding to the ferric ion (Fe3+) with the affinity (K = 1052 M-1). This value is substantially larger than even some synthetic metal chelators such as EDTA (KfFe3+ ~ 1025 M−1).
