Part of the ABC transporter complex AraFGH involved in L-arabinose import. Responsible for energy coupling to the transport system (Probable). ATP + H2O + L-arabinose(out) = ADP + H(+) + L-arabinose(in) + phosphate The complex is composed of two ATP-binding proteins (AraG), two transmembrane proteins (AraH) and a solute-binding protein (AraF). Belongs to the ABC transporter superfamily. Arabinose importer (TC 3.A.1.2.2) family.
