FIG. 2. Comparison of the subunit structures of
dizinc-dependent exopeptidases and Sk AS. The color scheme for
the latter is the same as described for Fig. 1a. For the
exopeptidases, the secondary structure elements are shown in
blue ( -strands) and red ( - and
3[10]-helices). The zinc ions are depicted as purple (for Sk
AS)
and blue (for exopeptidases) spheres.
