a, b, Cryo-EM density map and overall structure of the GlyT1 in the inward-facing apo state (GlyT1Apo-in). Micelle is colored grey, GlyT1 is colored light pink, and TM1 is highlighted with hot pink. N- and C- termini are labeled with spheres colored hot pink and light pink, respectively. c Surface electrostatic potential map of the GlyT1Apo-in. Unwound TM1a and TM6b form a vestibule toward the intracellular side.
