Figure 7

Orientation-selective Q-band CW 13C-ENDOR spectra (solid lines) and simulations (dashed lines) for 13CN−-bound oxidized D. vulgaris 2Fe-SOR (left panel) and P. furiosus 1Fe-SOR (right panel). The conditions are same as in Figure 6 except more scans were taken at weak ENDOR signals. Simulation parameters : EPR linewidth = 500 MHz; A and g tensors are coaxial; (1) for 2Fe-SOR: ENDOR linewidth: 1.5 MHz (C1 species) and 2.0 MHz (C2 & C3 species); (2) for 1Fe-SOR: ENDOR linewidth: 1.3 MHz (C1 species) and 2.0 MHz (C2 & C3 species).
