Part of the ABC transporter complex YtfQRT-YjfF involved in galactofuranose transport (Probable). Probably responsible for the translocation of the substrate across the membrane (Probable). The complex is composed of two ATP-binding proteins (YtfR), two transmembrane proteins (YtfT and YjfF) and a solute-binding protein (YtfQ). Belongs to the binding-protein-dependent transport system permease family. AraH/RbsC subfamily.
