摘要

The structure of the peripheral light-harvesting complex from Rhodopseudomonas acidophila strain 10050 was determined by multiple isomorphous replacement methods. The derivatization of the crystals was augmented by the addition of a backsoaking stage. The soak/backsoaked data comparison had greater isomorphism and showed simpler Patterson maps than the standard native/soak comparison. Amplitudes from the derivatized then backsoaked crystals and from the derivatized crystals were compared in order to extract a subset of heavy-atom sites. Using this information, the full array of sites were found from a derivative/native comparison, eventually leading to excellent electron-density maps.
