Figure 3
[sigma]A-Weighted 2Fo - Fc (blue) and [sigma]A-weighted Fo - Fc (positive, green; negative, red) electron-density maps. The [sigma]A-weighted 2Fo - Fc (blue) maps are contoured at 3.0[sigma], and the [sigma]A-weighted Fo - Fc maps are contoured at 2.1[sigma]. (a) Hydrogen-omit electron-density map around residue Tyr116 and (b) around residue Asn28. This figure was produced using the program PyMOL.  [article HTML]
