(a) Comparison of the Fe K-edge EXAFS data (inset) and their corresponding Fourier transforms for resting ferric forms of hemoglobin (black line) (Wilson et al., 2013), MauG (a heme-containing methylamine utilization protein) (red line) (Jensen et al., 2012), CCP (cytochrome c peroxidase) (blue line) (Jensen et al., 2012) and HO2 (heme oxygenase-2). (b) Structural schematic of the active site. The structures differ in the peripheral R groups, which are located ∼5 Å from the Fe center and have negligible contribution to the EXAFS data. These R groups have been truncated to methyl groups for simplicity of presentation. |
