Figure 7
TaB-derivative crystals of MUAE. A stereo representation of a section of the experimental electron-density map is shown after phase extension to 2.8 Å resolution, solvent flattening and threefold NCS averaging calculated from SAD phases (blue mesh, contoured at 1[sigma]) together with the anomalous difference Fourier map of tungsten (orange mesh, contoured at 5[sigma]). The C[alpha] trace of the final model (PDB entry 1z7l ) is shown as ribbon representation (black). The TaB cluster at binding site 1 was found by MR at 3.3 Å resolution and is shown in stick representation.  [article HTML]
