Figure 5 Results of the best fits of the cubic k-weighted EXAFS for (A) met-Hc and (B) met-azido-Hc derivatives from O. vulgaris and for (C) met-Hc and (D) met-azido-Hc derivatives from C. aestuarii. The total simulated signals (continuous line) are superimposed on the experimental signals (dotted line). At the bottom of panels the residual functions are plotted. The values of Rexp and Rth are reported. Biophysical Journal 2002 82, 3254-3268DOI: (10.1016/S0006-3495(02)75667-1) Copyright © 2002 The Biophysical Society Terms and Conditions

Figure 6 Comparison of the Cu K-edge XANES spectra (upper panel) and of the corresponding XANES derivative spectra (lower panel) for the met-Hc and met-azido-Hc derivatives from O. vulgaris and C. aestuarii.
