A central section in parallel to the membrane in the membrane inlayed region has an part of ~8 9 nm2. by cryo-EM and solitary particle image reconstruction. The structure discloses several domains within the extracellular part, three solvent-accessible low-density cavities and a potential substrate-binding surface groove in the transmembrane region of the complex. == Intro…
