Abstract
Trigonal crystals of photosynthetic reaction centres from the wild-type purple bacterium, Rhodobacter sphaeroides (ATCC 17023), have been grown from potassium phosphate solutions at 18 degrees C. They belong to the space group P3(1/2)21 and have unit cell dimensions of a = b = 141.4 A and c = 187.2 A. The crystals diffract to at least 2.65 A resolution and are suitable for detailed structural studies.
摘要
来自野生型紫色细菌球形红杆菌（ATCC 17023）的光合反应中心的三角晶体，已在18摄氏度下从磷酸钾溶液中生长出来。它们属于空间群P3(1/2)21，晶胞尺寸为a = b = 141.4埃，c = 187.2埃。这些晶体的衍射分辨率至少为2.65埃，适合进行详细的结构研究。
