Figure 3
Amplitude of the Fourier transform of the experimental data collected at room temperature for TLS (2 His) and SOD (3 His). Together with these experimental data we show as shadowed areas the sum of all the contributions, coming from the His residues in the theoretical calculations, and localized in the region 3–4 Å in R-space. The theoretical calculations were based on the target clusters of the database corresponding to the binding motif His His Glu H2O and His His His Asp, for TLS and SOD, respectively. The numerical values obtained for the integral I are reported in Table 3. |
