Reaction: ATP + H2O + Fe3+-enterobactin complex-[enterobactin-binding protein][side 1] = ADP + phosphate + Fe3+-enterobactin complex[side 2] + [enterobactin-binding protein][side 1]
Other name(s): ferric enterobactin transporting ATPase; ferric enterobactin ABC transporter; fepBCDG (gene names)
Systematic name: ATP phosphohydrolase (ABC-type, iron(III) enterobactin-importing)
Comments: An ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. A bacterial enzyme that interacts with an extracytoplasmic substrate binding protein and mediates the high affinity uptake of Fe3+-enterobactin complexes.
