Figure 20
Electron density as a cloud (3hyd , cutoff 1.6 e Å−3 or σ = 1.0). Simply by eliminating data points with values below a specified cut-off value, the structure of the protein backbone and, among others, a tyrosine side chain (top center) emerges. The surface enclosing these points would be the commonly drawn isosurface associated with a standard electron-density map.
