Abstract: Photoactivated phytochromes Phytochromes are a family of bilin-containing photoreceptors that regulate various processes in plants and microorganisms. These photoreceptors interconvert between a red-light-absorbing ground state (Pr) and a far-red-light-absorbing photoactivated state (Pfr). The structures of the Pr state of several phytochromes have been determined, but little is known about the Pfr state. In this paper, the authors determined that light-induced rotation of the A ring of the bilin is the primary motion of the chromophore during photoconversion. Subsequent rearrangements within the protein then affect intra- and interdomain contact sites within the phytochrome dimer.
