Part of the ABC transporter complex AraNPQ involved in the uptake of arabinooligosaccharides (By similarity). Responsible for the translocation of the substrate across the membrane (By similarity). The complex is composed of two ATP-binding proteins (MsmX), two transmembrane proteins (AraP and AraQ) and a solute-binding protein (AraN). Belongs to the binding-protein-dependent transport system permease family. MalFG subfamily.
