Figure 3 Stereo view (Kraulis, 1991) of a C[ ]trace
of the BM-40 I,
C
structure showing the residues that were mutated in this study
(see text). Disulfide bridges are shown with thick bonds.
Mutated residues are identified by position numbers and their
side chains. The three calcium ions are shown as black spheres.
