Figure 5
Hydrogen-bond network around Asp52. Yellow dashed lines represent hydrogen bonds or other interactions. The numbers denote the distances in Å. Atoms are shown as sticks (green, carbon; red, oxygen; blue: nitrogen). The O atom of the water molecule is shown as a red sphere. The electron-density maps are shown as blue contour lines for the protein (2Fo − Fc map at 1.5σ). |
