title: My daily constitutional in martinsried.
abstract: The three-dimensional structures of bacterial reaction centers have served as the framework for much of our understanding of anoxygenic photosynthesis. A key step in the determination of the structure of the reaction center from Rhodobacter sphaeroides was the use the molecular replacement technique. For this technique, we made use of two sets of data. First, X-ray diffraction data had been measured from crystals of the reaction center from R. sphaeroides by our research group in California, led by George Feher and Douglas Rees. The second data set consisted of the coordinates of the three-dimensional structure of the reaction center from Rhodopseudomonas (now Blastochloris) viridis, which had been solved in the pioneering efforts of a group in Martinsried, led by Johann Deisenhofer, Robert Huber and Hartmut Michel. The collaborative efforts of these two groups to determine the structure of the reaction center from R. sphaeroides is described.
