Reaction catalysed
  • Fe(III)-di(C-5-deoxy-beta-D-glucosyl)-enterobactin + H2O = Fe(III)-{N-(2,3-dihydroxybenzoyl)-L-seryl-[N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine]2} + H(+)
  • Fe(III)-C-5-deoxy-beta-D-glucosyl-enterobactin + H2O = Fe(III)-{di[N-(2,3-dihydroxybenzoyl)-L-seryl]-N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine} + H(+)
  • Fe(III)-{N-(2,3-dihydroxybenzoyl)-L-seryl-[N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine]2} + H2O + H(+) = Fe(III)-[N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine]2 + N-(2,3-dihydroxybenzoyl)-L-serine
  • Fe(III)-{N-(2,3-dihydroxybenzoyl)-L-seryl-[N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine]2} + H2O + H(+) = Fe(III)-{N-(2,3-dihydroxybenzoyl)-L-seryl-N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine} + N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine
  • Fe(III)-{di[N-(2,3-dihydroxybenzoyl)-L-seryl]-N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine} + H2O + H(+) = Fe(III)-{N-(2,3-dihydroxybenzoyl)-L-seryl-N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine} + N-(2,3-dihydroxybenzoyl)-L-serine
  • Fe(III)-[N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine]2 + H2O + H(+) = Fe(III)-[N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine] + N-(C-5-[deoxy-beta-D-glucosyl]-2,3-dihydroxybenzoyl)-L-serine
Comment(s)
  • This bacterial enzyme is present in pathogenic Salmonella species, uropathogenic and avian pathogenic Escherichia coli strains, and certain Klebsiella strains.
  • The enzyme acts on iron(III)-bound enterobactin and C-glucosylated derivatives known as salmochelins.
  • Unlike EC 3.1.1.107, (IroE), IroD prefers iron(III)-bound siderophores as substrates, and is assumed to act after the iron- siderophore complexes are imported into the cell.
  • It catalyzes several hydrolytic reactions, producing a mixture of iron(III)-[N-(2,3-dihydroxybenzoyl)-L-serine] complex and salmochelin SX.
