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 (BOV_A0347 and BOV_A0348), two transmembrane proteins (BOV_A0350 and BOV_A0351) and a solute-binding protein (BOV_A0352). Belongs to the binding-protein-dependent transport system permease family.
