A comparison of the Fe(V)-equivalent intermediates in CCP-I and bisFe(IV) MauG. The second electron equivalent is on a Trp residue in CCP-I, whereas it is delocalized onto Tyr294. The green arrows point to the π pathway (heme A–Trp93–heme B–Tyr294) for electron transfer. The closest distances (the atoms between which the distances were measured have been marked with an asterisk) from the Trp rings to the heme centers are shown
