Figure 6
Comparison of the fitting of (a) AMPP—NH—P or (b) AMPP—N=P into a structure. In (c) the imido (P—NH—P) form was fitted into an FoFc ligand-omit map (shown at 6.5σ), while in (d) and (f) the imino (P—N=P or P—N—P) form was fitted into the same map (see Table 1[link] for restraints). Small overlaps and bad overlaps are displayed as dots. (e) shows that there are only small differences between the fitted coordinates from (c), (d) and (f) and the deposited structure (PDB entry 1pvg; the four structures are shown superposed). (a) and (b) were drawn with Marvin ( and (c), (d), (e) and (f) with Coot (Emsley et al., 2010BB23).
