Figure 5. (Upper panel) Relaxed stereodiagram of an overlay of
the turn 1 (CPK color scheme) and turn 5 (gray) regions in
wild-type FGF-1 (PDB accession 1JQZ). (Lower panel) Relaxed
stereo diagram of an overlay of the turn 1 (CPK color scheme)
and turn 5 (gray) regions in the S17T/N18T/  G19
and E60
mutants, respectively. The structural similarity of these
symmetry-related turns is retained as they are converted from
type I 4:6 to type I 3:5 turns.
