Figure 3
Electron density from AcNiR Cu-SAD experiments at the SLS using λ = 0.75 Å, calculated from SHELXE and following density modification by DM. The map covers the same section as in Fig. 1(b) and is shown at (a) 1.25 Å resolution contoured at 1.2σ (0.80 electrons Å−3) and (b) 2.2 Å resolution contoured at 1.1σ (0.69 electrons Å−3). |
