Part of the ABC transporter complex AraNPQ involved in the uptake of arabinooligosaccharides. Transports alpha-1,5-arabinooligosaccharides, at least up to four L-arabinosyl units (PubMed:20693325). Responsible for the translocation of the substrate across the membrane (Probable). The complex is composed of two ATP-binding proteins (MsmX), two transmembrane proteins (AraP and AraQ) and a solute-binding protein (AraN). Transcription is repressed by glucose and by the binding of AraR to the operon promoter. L-arabinose acts as an inducer by inhibiting the binding of AraR to the DNA, thus allowing expression of the gene. Belongs to the binding-protein-dependent transport system permease family. MalFG subfamily.
