The histogram-phased 16 Å resolution Fourier synthesis (39 independent reflections) for RNAse Sa overlapped with Cα-atom positions in (a) molecules linked to the molecule A by space-group symmetries, (b) the same for the molecule B. The projection through the unit cell along the z axis is shown. The cutoff level isolates a volume equal to 20 Å3 per residue. |
