ENZYME entry: EC

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)
  • This bacterial enzyme is present in pathogenic Salmonella species, uropathogenic and avian pathogenic Escherichia coli strains, and certain Klebsiella strains.
  • Unlike EC, which acts only on enterobactin, this enzyme can also act on the C-glucosylated forms known as salmochelins.
  • Unlike EC, (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.
