FIGURE 2. Stoichiometric binding between the WSCP monomer
and Chl. Chains A and B of the WSCP tetramer and Chl-1 are shown
in ribbon models and a stick model, respectively, with the same
color coding as in Fig. 1. The [A]-weighted 2F[o] -
F[c] electron density map (4.0 contour) for the
central Mg^2+ ion is shown in pink mesh. The water molecule in
the Chl-binding cavity forms two hydrogen bonds (pink lines).
Chl-2 is omitted for clarity.
