Figure 2.
Figure 2. Isomorphous and anomalous difference Fourier maps
using selenomethionine data, superimposed on a backbone
representation of the two molecules within the asymmetric unit.
Experimental phases from the two mercury derivatives were used
in map calculation; both maps are contoured at 5s. The ten
selenium sites in the asymmetric unit are labelled according to
the methionine residue number. (The figure was produced using
the program SETOR [40].)
