Fig. 8. Experimentally-phased electron density maps for (a) pb6 at 2.85 Å resolution and (b) MDH at 2.35 Å resolution. The maps are contoured at 1.0 sigma. The Calpha trace corresponds to the automatically built model. (c) The packing of pb9 crystals (asymmetric unit content in black, symmetry-related molecules in grey). All of the Tb positions are shown with spheres. Details of the main Tb–Xo4 binding sites are shown in close-up views. pb9 PDB ID code ; 5MF2.
