Figure 6 Stereoview of the superposition of Y43F on wild-type
streptavidin. Unbound Y43F in light blue, bound Y43F in dark
blue and wild-type streptavidin in yellow. The binding site in
the unbound Y43F structure is occupied by a water molecule and
an MPD molecule (Freitag et al., 1999[Freitag, S., Le Trong, I.,
Klumb, L. A., Stayton, P. S. & Stenkamp, R. E. (1999). Acta
Cryst. D55, 1118-1126.]). Figure drawn with MOLSCRIPT (Kraulis,
1991[Kraulis, P. J. (1991). J. Appl. Cryst. 24, 946-950.]) and
Raster3D (Merritt & Bacon, 1997[Merritt, E. A. & Bacon, D. J.
