Part of the histidine permease ABC transporter. Binds histidine. Interacts with HisQMP and stimulates ATPase activity of HisP, which results in histidine translocation. May have some additional function(s) in translocation that is independent of the stimulation of ATP hydrolysis. The complex is composed of two ATP-binding proteins (HisP), two transmembrane proteins (HisM and HisQ) and a solute-binding protein (HisJ). Belongs to the bacterial solute-binding protein 3 family.
