Figure 7
Model and extracted density around three residues in a 2.2 Å resolution cryo-EM map of β-galactosidase (EMDB entry EMD-2984, PDB entry 5a1a). The cryo-EM map is shown in (a) and maps generated from models with B factors with different methods in (b)–(d). (e) shows real-space cross-correlations between the entire cryo-EM map and model maps with B factors calculated using REFMAC, Phenix and Q-scores. |
