Figure 3: Recognition of GA[3] by GID1A. a, A top view of the
GID1A-bound GA[3]. GID1A residues that contact GA[3] are
highlighted in yellow (the core domain) or cyan (the N-terminal
extension) and shown as stick models with van der Waals surfaces
(dots) and hydrogen bonds (dotted lines). Omit electron density
for GA[3] is shown in 3.5 contour
(red). b, A side view showing nonpolar contacts between
N-terminal extension helix b
and the GA[3] aliphatic rings. c, A top view of the hydroxyl
groups of GA[3]. d, The bound GA[3] (green) superimposes onto
GA[4] (pink) with a small root mean squared deviation (0.20
Å). Water molecules are shown as blue or red spheres.
