Figure 5
Active-site comparison of CA IX_SV. (a) H/H in the small P2₁ unit cell, (b) H/H in the doubled P2₁ unit cell, (c) H/D exchanged in the small P2₁ unit cell and (d) D/D CA IX_SV in the small P2₁ unit cell. Active-site residues are depicted as yellow sticks; water molecules and Zn atoms are shown as red and magenta spheres, respectively. 2F_o − F_c electron-density maps are shown in blue mesh and are contoured at 1.50σ for residues, 1.25σ for solvent and 3.50σ for zinc.
