Figure 6
Comparison of various maps in the binding site of analogues 7H2, 7H2_AL1 and 7H2_AL2 (row 1 to row 3, respectively). (a, d, g) PanDDA event maps (BDC = 0.34, 0.33 and 0.48, respectively) and Z-maps (green/red, ±4.0σ). (b, e, h) Chlorine, bromine and iodine anomalous difference Fourier maps calculated from data collected at 4.5 keV (orange, 4σ) overlaid with mFo − DFc maps (green, 3.0σ) calculated from the 12.8 keV data in the fragment region. (c, f, i) Refined 2mFo − DFc maps (blue, 1.0σ) of 7H2, 7H2_AL1 and 7H2_AL2 calculated from the 12.8 keV data with the Cl, Br or I atom placed in the centre of the anomalous peaks. The electron density mostly accounts for 7H2, while for the two analogues the density systematically degrades, possibly due to their low occupancy. |
