Figure 24
A series of images from a crystal of lysozyme with unit-cell parameters a = 78.6, c = 37.2 Å in space group P43212 at 2.7 Å resolution with 1.5° rotation per exposure. (a)–(d) Four consecutive images exposed with the crystal oriented along its fourfold axis. Large gaps between lunes result from a short c axis. (e, f) Two images exposed 90° away, along the 110 direction. The lunes are much wider, overlapping at high resolution. A close inspection of the zero-layers reveals the presence of systematic absences resulting from the 21 axes (c and d) and the 43 axis (e and f).
