Refined ADC and lysozyme structures showing that residues susceptible to radiation damage remained intact. The 2Fo − Fc electron-density map (blue mesh) is contoured at 1 r.m.s.d. The Fo − Fc map (red/green mesh, contoured at 4 r.m.s.d.) is shown but no difference density is visible. (a) The surface glutamate (residue 96) of ADC. (b) The disulfide bond between residues 6 and 127 of lysozyme. |
