Fig. 6. The
S1 (Ca 2+)
and
$2 (Cd 2+)
metal sites. Both sites have
octahedral-like geometry with Aspl0 capping an axial position
of the Ca 2÷ ion. Aspl9 and Aspl0 are bound to both metals.
Asp208
is shown and it makes hydrogen bonds with
WC
which
are thought to stabilize the
cis
peptide. The two metal ions are
separated
by 4.18/~,.
