General annotation (Comments)

Function	Part of the ABC transporter complex fhuCDB involved in iron3+-hydroxamate import. Responsible for energy coupling to the transport system. Ref.7
Catalytic activity	ATP + H2O + iron chelate(Out) = ADP + phosphate + iron chelate(In).
Subunit structure	The complex is composed of an ATP-binding protein (fhuC), two transmembrane proteins (fhuB) and a solute-binding protein (fhuD).
Subcellular location	Cell inner membrane; Peripheral membrane protein. Ref.7
Sequence similarities	Belongs to the ABC transporter family. Iron (Fe3+)-hydroxamate importer (TC 3.A.1.14.7) subfamily. [View classification] Contains 1 ABC transporter domain.
