Part of the histidine permease ABC transporter. Also part of a lysine/arginine/ornithine transporter. Responsible for energy coupling to the transport system. ATPase activity is slightly increased in the presence of HisM and HisQ, and strongly increased when HisJ is also present. The complex is composed of two ATP-binding proteins (HisP), two transmembrane proteins (HisM and HisQ) and a solute-binding protein (HisJ or ArgT). Binds much more tightly to the membrane in the presence of HisQ and HisM. Belongs to the ABC transporter superfamily.
