IUBMB Enzyme Nomenclature


Accepted name: ABC-type Fe3+ transporter

Reaction: ATP + H2O + Fe3+-[iron-binding protein][side 1] = ADP + phosphate + Fe3+[side 2] + [iron-binding protein][side 1]

Other name(s): Fe3+-transporting ATPase

Systematic name: ATP phosphohydrolase (ABC-type, Fe3+-transporting)

Comments: ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains. A bacterial enzyme that interacts with a periplasmic iron-binding protein to imports Fe3+ ions into the cytoplasm.
