Superimposition of GluTR monomers.
(A) Superimposed backbones of the four GluTR monomers. The color schemes are green for chain (A) of 5CHE, light green for chain (B) of 5CHE, prussian blue for chain (A) of 4N7R and cyan for chain (B) of 4N7R. Orange arrows denote structural difference in the dimerization domain. (B) Superimposed backbones of the spinal helix and the dimerization domain of the two GluTR dimers. The two arms of the Y-shaped GluTR dimer in the ternary complex are denoted by solid orange lines; the two arms in the GluTR-GBP binary complex are denoted by dashed orange lines.
