Figure 1.
Figure 1 Electron density for a helix of terminal protein near the active site of polymerase. On the left is a 3.5 Å resolution map contoured at 1 using data from the I23 crystal form. It was calculated using amplitudes sharpened by a factor of 100 and experimentally phased with solvent-flattened heavy-atom phases. Side chains cannot be unambiguously assigned in this map. On the right is a composite omit map contoured at 1 and calculated to 3 Å using data from the C2 crystal form. Side chain density is much better defined in this map. Figures 1, 2, 3A, 3B, and 4 were made using Pymol (http://www.pymol.org).
