ATP + H2O + iron chelateout = ADP + phosphate + iron chelatein
ATP phosphohydrolase (iron-chelate-importing)
ABC-type (ATP-binding cassette-type) ATPase, characterized by the presence of two similar ATP-binding domains. Does not undergo phosphorylation during the transport process. A bacterial enzyme that imports Fe-enterobactin, Fe-dicitrate, Fe-hydroxamate and other siderophores.
