Part of the ABC transporter complex ArtPIQMJ involved in arginine transport. Probably responsible for the translocation of the substrate across the membrane (By similarity). The complex is composed of two ATP-binding proteins (ArtP), two transmembrane proteins (ArtM and ArtQ) and two solute-binding proteins (ArtJ and ArtI). Belongs to the binding-protein-dependent transport system permease family. HisMQ subfamily.
