XANES spectra of Escherichia coli flavohemoglobin. Normalized Fe K-edge XANES spectra of lipid-free HMP (HMP_LF) and lipid-bound HMP (HMP_LB). Continuous lines refer to the best fitting theoretical curves obtained from the MXAN refinement (see Materials and Methods). Bottom spectra represent the comparison between the theoretical curves of lipid-free HMP (solid line) and lipid-bound HMP (dashed line).
