ENZYME entry: EC 3.1.1.107
| Accepted Name |
|---|
| Apo-salmochelin esterase.
|
| Reaction catalysed |
|---|
- Enterobactin + H(2)O <=> N-(2,3-dihydroxybenzoyl)-L-serine trimer
- Triglucosyl-enterobactin + H(2)O <=> triglucosyl-(2,3-dihydroxybenzoylserine)(3)
- Diglucosyl-enterobactin + H(2)O <=> diglucosyl-(2,3-dihydroxybenzoylserine)(3)
- Monoglucosyl-enterobactin + H(2)O <=> monoglucosyl-(2,3-dihydroxybenzoylserine)(3)

| 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.
