Simulations of Cu K-edge EXAFS data from frozen solutions of CuZn bovine SOD. (a) The reduced EXAFS, fitted using coordinates from the atomic-resolution (1.15 Å) crystal structure (Hough & Hasnain, 2003), with three histidine ligands coordinated at 1.96, 2.03 and 2.06 Å. (b) The oxidized EXAFS using crystal structure coordinates from a 1.65 Å resolution data set, with four histidine ligands and a water molecule at 2.0, 2.15, 2.21, 2.21 and 2.54 Å, respectively (Hough & Hasnain, 1999). |
