Figure 4
Electron-density maps of the Cys76—Cys94 disulfide bond in HEWL crystals. The Fo–Fc maps are weighted and are contoured at : (a) is calculated from the first data set from the native HEWL crystal, (b) is calculated from the sixth data set from the native crystal, (c) is calculated from the first data set from the crystal grown in the presence of ascorbate and (d) is calculated from the sixth data set from the crystal grown in the presence of ascorbate. The figure was produced using MOLSCRIPT (Kraulis, 1991), CONSCRIPT (Lawrence & Bourke, 2000) and RASTER3D (Merritt & Bacon, 1997). |
