Part of the ABC transporter complex YfiYZ/YfhA/YusV involved in import of the iron-hydroxamate siderophores schizokinen, arthrobactin and corprogen. The complex is composed of one ATP-binding protein (YusV), two transmembrane proteins (YfiZ and YfhA) and a solute-binding protein (YfiY). Induced by iron starvation, repressed by fur. Strains lacking this gene show a reduction in growth stimulation by the iron-hydroxamate siderophores schizokinen and arthrobactin compared to wild-type. Belongs to the binding-protein-dependent transport system permease family. FecCD subfamily.
