Figure 1 Stereoview of the 2Fo - Fc electron densities contoured at 1.0. Each residue around Tyr146 (center) is shown as a stick model (C atoms, yellow; N atoms, blue; O atoms, red; S atoms, orange). Water molecules are shown as red spheres. Grey sticks show the residues of a symmetry-related molecule.
