Figure 4.
Fig. 4. Electron transfer region between the [2Fe-2S]
cluster of Adx and the FAD moiety of AR. The hypothetical
electron pathway shown in red was calculated with the program
HARLEM (31). Red dotted lines mark through-space electron jumps.
The AR-Adx interface is stabilized by hydrogen bonds (blue
dotted lines) and van der Waals contacts. Residues are labeled
black for AR and red for Adx. The blue spheres are water
molecules.
