Figure 4
Relaxed stereoviews of the Sr2+- and Cs+-binding sites identified for NQ-HaBLA. (a), (b) and (c) show the site 2, site 6 and site 7 Sr2+-binding sites, respectively, observed in condition 2A (0 mM Ca2+/200 mM Sr2+). (d), (e) and (f) show the site 8 Cs+-binding site observed in condition 1A (0 mM Na+/100 mM Cs+), in condition 1B (75 mM Na+/25 mM Cs+) and in condition 1C (90 mM Na+/10 mM Cs+), respectively. (g) shows site 8 in the crystal structure without soaking (100 mM Na+/0 mM Cs+) as a control. The colours of chains A, B and C and of the metal ions are the same as those in Fig. 1 ![[link]](../../../../../../logos/arrows/d_arr.gif) . In (a) and (c), chains generated by a crystal symmetry operator are indicated by an asterisk after the chain name. The blue meshes in (a), (b), (c), (d), (e) and (f) show the anomalous difference Fourier map within a 5σ contour level. The green mesh in (g) shows a 2Fo − Fc OMIT map within a 2σ contour level. |
