The photochemical reaction center from Rhodobacter sphaeroides 2.4.1 has been crystallized. The crystals were obtained in a solution of beta-octylglucoside by the vapor diffusion technique using polyethylene glycol 4000 as the precipitant at 22 degrees C. The orthorhombic crystals (space group P2(1)2(1)2(1)) have cell constants a = 142.5 A, b = 136.1 A, c = 78.5 A, and diffract to 3.7 A. The crystals display pronounced linear dichroism in the carotenoid absorption spectral region.
球形红杆菌2.4.1的光化学反应中心已被结晶。通过气相扩散技术，以聚乙二醇4000作为沉淀剂，在β-辛基葡糖苷溶液中于22℃获得晶体。正交晶体（空间群P2(1)2(1)2(1)）的晶胞常数为a = 142.5 Å，b = 136.1 Å，c = 78.5 Å，衍射极限为3.7 Å。这些晶体在类胡萝卜素吸收光谱区域表现出明显的线性二色性。
