Fig. 6. Conformational changes from outward-open to inward-open.
a Superposition of hSGLT1outward-oepn (colored) and hSGLT1inward-open (gray, PDB ID: 7SLA). Helices are shown as cylinders. b The structural alignment of the constant module. c Top view of the moving module. d Bottom view of the moving module. The movement of helices are shown as red arrows. e The conformational changes of the hSGLT1 extracellular gate. f The conformational changes of the hSGLT1 intracellular gate. Residues which moves are shown as sticks, the movement of residues are shown as red arrows.
