Figure 10

For Ribonuclease A (PDB file 5RSA), which performs its function even in its crystalline form [5], the asymmetric unit (a) and its unit cell (b) are largely flexible. In contrast, a derivative of the protein, which is known to lose virtually all activity [26], the asymmetric unit (c) and unit cell (d) are both very rigid, and contain far more atoms in the dominant rigid cluster than the structure in file 5RSA.
