Solution and refinement of a tetragonal HEWL structure. (a) Electron-density maps (2FoFc at 1.0σ, blue mesh; FoFc at 2.5σ, green mesh) obtained from molecular replacement using a polyalanine model of tetragonal HEWL. (b) Final refined 2FoFc map (1.5σ, blue mesh) of tetragonal HEWL at 2.5 Å resolution. (c) Ramachandran diagram of all amino-acid residues in the asymmetric unit. (d) Superposition of the tetragonal HEWL structure determined from in-chip diffraction data (orange) versus 15 tetragonal HEWL structures randomly drawn from the Protein Data Bank (grey).
