Stick structure of (GlcNAc)4 bound to lysozyme in D2O with electron-density maps (green, carbon; red, oxygen; blue, nitrogen). NAG1, NAG2, NAG3 and NAG4 correspond to the first, second, third and fourth residue of (GlcNAc)4, respectively. The blue and olive electron-density maps are 2Fo − Fc at 1.5σ and Fo − Fc at 3.0σ, respectively, which were drawn by omitting NAG4. |
