FIGURE 5.
Correlation diagrams for selected interactions. Left panel: the combined mean value of His-411-Gly-386/Thr-389 distance and mean value for His-411-Gly-386 distance. Right panel: the effect of the variation in Fe(IV)=O (ferryl) and Fe-N (His-411) bond lengths on the ν(Fe=O) mode. The abbreviations used are: C, fully deprotonated propionate-A/Asp-399 pair; A, fully protonated propionate-A/Asp-399 pair; D, only the propionate-A is protonated; B, only Asp-399 is protonated; GH, Glu-278 is protonated.
