Figure 1
Comparing the same electron-density features at 4, 3, 2 and 1 Å resolution for crystal structures of apo T4 lysozyme. At the top is the helix Ile58–Gly77 and at the bottom is the loop Asn132–Trp138. The left panel is PDB entry 4gbr at 3.99 Å resolution (Zou et al., 2012  ), the second panel is PDB entry 5zbh at 3.0 Å resolution (Yang et al., 2018), the third panel is PDB entry 1lyi at 2.0 Å resolution (Bell et al., 1992) and the right panel is PDB entry 5jdt at 1.0 Å resolution (Consentius et al., 2016). All are wild type except for a Thr59→Asp mutation in PDB entry 1lyi. The σA-weighted 2Fo − Fc maps are contoured at 1.2σ (gray) and 3σ (purple). |
