Cytochrome c2 from Rhodobacter sphaeroides, which serves as the secondary donor in bacterial photosynthesis, has been crystallized from ammonium sulfate solutions at pH 7.0 by vapor diffusion. The crystals are well formed with clearly discernable facets. Their space group is P6522 (or its enantiomorph P6122) with unit cell dimensions a = b = 64.5 A ̊ and c = 163.0 A ̊, and two proteins per asymmetric unit. The crystals diffract to at least 2.7 Å and are stable during X-ray exposure for several days.
