Figure 1

Photochemical reaction scheme for EcPL which provides a framework for discussing the photocycle of DmCry. The curly green arrows represent the magnetically-sensitive coherent interconversion of the singlet and triplet states of RP1. The photocycle of AtCry1 differs only in that RP2 is believed to contain the protonated radical FADH rather than FAD•−.
