Figure 8. Stereo view showing the overlap of the flexible
binding loop in the wild-type core-streptavidin-biotin complex
(pink bonds) with residues near the C terminus of T7-SA (blue
bonds). Residues 154-156 in T7-SA, while not actually bound in
the biotin-binding site, take on the same conformation and
nearly the same location as the closed loop in the
wild-type-biotin complex.
