Figure 1
The superposition of the rigid-body-refined insulin molecule model and the S-SAD-phased experimental 2fo − fc electron-density map at 50.0–2.5 Å resolution contoured at 1.0σ. (a) The map was calculated using the regular-exposed data of crystal 1. The arrow signs in the figure indicate the missing density at the main-chain area. (b) The map was calculated using the MDS-exposed data of crystal 1. |
