Xylanase II structure. Left, secondary structure with selected residues; right, selected residues with 1.5 Å resolution σA-weighted 2Fo − Fc electron-density map contoured at 0.7 e Å−3 level. The excellent densities for beam-sensitive residues, for example glutamic acids, tyrosines and methionine, provide no evidence of radiation damage. |
