| Research Abstract |
Toward investigation of the structure and function of phytochromes as photoreceptive chromoproteins regulating photomorphogenesis in plants, we have developed an efficient and flexible method for the preparation of chromophores (PΦB, PCB, and BV) of phytochromes, and have found a lot of insights into phytochromes. For example, we could directly reveal the stereochemistry of the chromophore in red light absorbing Pr-form and far-red light absorbing Pfr-form of Agrobacterium phytochromes, Agp1 and Agp2, by the assembly experiments of the chemically synthesized locked chromophores with apophytochromes.
