ID   3.1.1.107
DE   apo-salmochelin esterase.
CA   (1) enterobactin + H2O = N-(2,3-dihydroxybenzoyl)-L-serine trimer.
CA   (2) H2O + triglucosyl-enterobactin = [N-(C-5-[deoxy-beta-D-glucosyl]-2,3-
CA   dihydroxybenzoyl)-L-serine]3 + H(+).
CA   (3) diglucosyl-enterobactin + H2O = H(+) + N-(2,3-dihydroxybenzoyl)-L-
CA   seryl-[N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine]2.
CA   (4) H2O + monoglucosyl-enterobactin = [N-(2,3-dihydroxybenzoyl)-L-
CA   seryl]2-N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine +
CA   H(+).
CC   -!- This bacterial enzyme is present in pathogenic Salmonella species,
CC       uropathogenic and avian pathogenic Escherichia coli strains,
CC       and certain Klebsiella strains.
CC   -!- Unlike EC 3.1.1.108, which acts only on enterobactin, this enzyme can
CC       also act on the C-glucosylated forms known as salmochelins.
CC   -!- Unlike EC 3.1.1.109, (IroD), IroE prefers apo siderophores as
CC       substrates, and is assumed to act before the siderophores are
CC       exported out of the cell.
CC   -!- It hydrolyzes the trilactone only once, producing linearized trimers.
