Figure 8
(a) Scan of the C23M_1 crystal at a range of energies showing a peak corresponding to the zinc absorption edge (top). Scattering factors (f′ and f′′) are plotted as a function of energy (bottom). (b) An anomalous omit electron-density map of the active-site region of C23M_1, contoured at 6σ, is shown in black. The two Zn²⁺ ions are shown as magenta spheres and were omitted in calculating the electron density.
