Figure 18.2.5.2
Maximum-likelihood targets significantly decrease model bias in simulated-annealing refinement. -weighted electron-density maps contoured at 1.25σ for models from simulated-annealing refinement with different targets are shown. Residues 233 to 237 are shown for the published penicillopepsin crystal structure (Hsu et al., 1977) as solid lines, and for the model with the lowest free R value from five independent refinements as dashed lines. |
