Probably part of an ABC transporter complex that could be involved in peptide import. Probably responsible for the translocation of the substrate across the membrane (By similarity). The complex is composed of two ATP-binding proteins (BruAb2_1033 and BruAb2_1034), two transmembrane proteins (BruAb2_1031 and BruAb2_1032) and a solute-binding protein (BruAb2_1030). Belongs to the binding-protein-dependent transport system permease family.
