Part of the ABC transporter complex AraFGH involved in 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). Induced by arabinose. Transcription is dependent on the transcription factor AraC, the cAMP receptor protein (CRP) and cAMP. Belongs to the ABC transporter superfamily. Arabinose importer (TC 3.A.1.2.2) family.
