IntEnz Enzyme Nomenclature


Accepted name:
ABC-type ferric enterobactin transporter
Other names:
ferric enterobactin transporting ATPase
ferric enterobactin ABC transporter
fepBCDG (gene names)
Systematic name:
ATP phosphohydrolase (ABC-type, iron(III) enterobactin-importing)



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. Formerly EC
