Figure 4

A simplified framework for interpreting the key kinetic and magnetic field effect data for DmCry assuming a tetrad of tryptophan residues. RP1C, RP1D, and RP2D represent radical pairs comprising FAD•− with TrpCH•+, TrpDH•+, and TrpD, respectively. The bold arrows represent major pathways.
