IUBMB Enzyme Nomenclature


Accepted name: Fe3+-transporting ATPase

Reaction: ATP + H2O + Fe3+out = ADP + phosphate + Fe3+in

Systematic name: ATP phosphohydrolase (ferric-ion-transporting)

Comments: ABC-type (ATP-binding cassette-type) ATPase, characterised by the presence of two similar ATP-binding domains. Does not undergo phosphorylation during the transport process. A bacterial enzyme that imports ferric cations.
