Figure 1

(Top) left: Cartoon representation of a single GltPh protomer with bound aspartate (sticks) and two Na+ ions (blue spheres). HP1, TM7, HP2 and TM8 containing ligand binding residues are shown in yellow, orange, red and violet respectively. (Top) right: extracellular view of GltPh with trimerisation domains shown in green and transport domains in blue. Individual protomers are separated by straight lines, whilst transport domains are separated from trimerisation domains by curved lines. (Bottom) a cartoon representation of the GltPh fold highlighting the residues involved in substrate binding. The protein images were prepared using PyMOL (The PyMOL Molecular Graphics System; https://www.pymol.org).
