Figure 2
(a) k3-weighted EXAFS and (b) radial distribution function calculated as the modulus of the phase-corrected Fourier transform of T6 nickel insulin. Experimental spectra are shown in blue and simulated spectra in grey (dashed lines) using the parameters from the restrained refinement given in Table 3. (c) Ni insulin XANES. The experimental XANES (blue) is compared with XANES calculated from a 4.5 Å cluster around the Ni atom using the refined coordinates from EXAFS (dashed line). |
