title: Crystallization and preliminary X-ray diffraction study of ferrocytochrome c2 from Rhodopseudomonas viridis.
abstract: Crystals of ferrocytochrome c2 from a non-sulphur purple photosynthetic bacterium, Rhodopseudomonas viridis, have been grown from ammonium sulphate solution at pH 8.5 by the sitting-drop vapour-diffusion procedure. The crystals belong to the trigonal system, space group P3(1)21 (or its enantiomorph P3(2)21) with unit-cell dimensions of a = b = 75.8 A and c = 40.1 A, and diffract to at least 2.0 A resolution. Assuming that an asymmetric unit contains one protein molecule (approx. 12,300 Mr), the solvent content of the crystal is approximately 54.5% (v/v).
