Part of the ABC transporter complex AraFGH involved in L-arabinose import. Responsible for the translocation of the substrate across the membrane (Probable). The complex is composed of two ATP-binding proteins (AraG), two transmembrane proteins (AraH) and a solute-binding protein (AraF). Belongs to the binding-protein-dependent transport system permease family. AraH/RbsC subfamily.
