title: Purification, crystallization and preliminary X-ray analysis of adenylylsulfate reductase from Desulfovibrio vulgaris Miyazaki F.
abstract: Sulfur in its various oxidation states is used for energy conservation in many microorganisms. Adenylylsulfate reductase is a key enzyme in the sulfur-reduction pathway of sulfate-reducing bacteria. The adenylylsulfate reductase from Desulfovibrio vulgaris Miyazaki F has been purified and crystallized at 277 K using the vapour-diffusion method with ammonium sulfate as the precipitating agent. A data set was collected to 1.7 A resolution from a single crystal at 100 K using synchrotron radiation. The crystal belonged to space group P3(1), with unit-cell parameters a = b = 125.93, c = 164.24 A. The crystal contained two molecules per asymmetric unit, with a Matthews coefficient (V(M)) of 4.02 A(3) Da(-1); the solvent content was estimated to be 69.4%.
