title: New crystal form of the photosynthetic reaction centre from Rhodobacter sphaeroides of improved diffraction quality.
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.
