title: A new crystal form and preliminary crystallographic data for ferricytochrome c' from Rhodospirillum rubrum.
abstract: A new crystal form of ferricytochrome c' from the photosynthetic bacteria, Rhodospirillum rubrum, has been obtained by dialysing protein solution against polyethylene glycol 4000. The crystals belong to the space group P61 (or its enantiomorph P65) with unit cell dimensions: a = b = 51.63 A and c = 155.39 A. The asymmetric unit contains one dimer molecule of 28,000 molecular weight and the solvent content of the unit cell is approximately 38%.
