Figure 5

Stereo drawing of the Fo − Fc electron-density map and residues around isoAsp28L in the unliganded isoAsp form (2.47 Å resolution). The map was calculated based on phases from the model without residues Ser27eL, isoAsp28L, and Gly29L and is contoured at 4 σ. The isoAsp28L and surrounding residues are also shown as stick models.
