EXAFS data and model fit. Magnitude of the Fourier transform (uncorrected for phase shift) of the k²-weighted 9453d EXAFS spectrum (blue) and first shell model fit (black). R-space fit performed from 1.3 to 2.4 Å. Inset right: k-space fit (2–11 Å⁻¹). Inset left: representation of 9453d Zn-binding site with distances labeled in yellow; original model based on 2GWG shown as thin lines (distances in red).
