FIG. 2. Fs1 structure. Left, ribbon diagram of the Fs1/SOS
structure, highlighting secondary structure elements. Right,
diagrams of the superimposed C[ ]traces for the Fs1
(red), Fs1/SOS (yellow), and Fs1/Ins6S (blue) structures; the
loop involved in crystal contacts is circled, and the SOS and
Ins6S are shown in stick representation. In both halves of this
figure, disulfide bonds are depicted in white with red
numbering, and secondary structure elements are labeled in dark
blue. This figure and the following three-dimensional
representations of molecules were generated using the program
Molscript (50) and rendered with Raster3D (51).
