Probably part of an ABC transporter complex that could be involved in peptide import. The complex is composed of two ATP-binding proteins (BMEII0205 and BMEII0206), two transmembrane proteins (BMEII0207/BMEII0208 and BMEII0209) and a solute-binding protein (BMEII0210). Belongs to the bacterial solute-binding protein 5 family.
