- enterobactin + H2O = N-(2,3-dihydroxybenzoyl)-L-serine trimer
- triglucosyl-enterobactin + H2O = [N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine]3 + H(+)
- diglucosyl-enterobactin + H2O = N-(2,3-dihydroxybenzoyl)-L-seryl-[N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine]2 + H(+)
- monoglucosyl-enterobactin + H2O = [N-(2,3-dihydroxybenzoyl)-L-seryl]2-N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine + H(+)

| Comment(s) |
|---|
- This bacterial enzyme is present in pathogenic Salmonella species,
uropathogenic and avian pathogenic Escherichia coli strains,
and certain Klebsiella strains.
- Unlike EC 3.1.1.108, which acts only on enterobactin, this enzyme can
also act on the C-glucosylated forms known as salmochelins.
- Unlike EC 3.1.1.109, (IroD), IroE prefers apo siderophores as
substrates, and is assumed to act before the siderophores are
exported out of the cell.
- It hydrolyzes the trilactone only once, producing linearized trimers.
