Fig. 2. Relaxed stereo diagram of the X-ray crystal
structures (molecule A in the asymmetric unit in each case) of
position 83 mutants of FGF-1 (CPK coloring) showing the
structural details adjacent to the site of mutation and overlaid
with the coordinates of wild-type FGF-1 (PDB code 1JQZ; light
gray). (a) Cys83 → Ala. (b) Cys83 → Ser. (c) Cys83 → Thr.
(d) Cys83 → Val. (e) Cys83 → Ile.
