|Abstract||Violacein, a natural purple secondary metabolite, is sequentially biosynthesized by five enzymes in the following pathway: VioA-VioB-VioE-VioD-VioC. VioD, a flavin-dependent oxygenase, catalyzes the hydroxylation of the intermediate product prodeoxyviolaceinic acid (PVA) at the 5-position of one indole ring to yield proviolacein. In vitro biochemical data have revealed this process, but the catalytic mechanism still remains largely unclear. Here, the cloning, expression, purification, crystallization and diffraction of VioD are reported. Crystals of VioD diffracted to 1.7 angstrom resolution and belonged to space group P3(1), with unit-cell parameters a = b = 90.0, c = 94.5 angstrom, alpha = beta = 90, gamma = 120 degrees. Solvent-content calculation and molecular-replacement results suggest the presence of two molecules of VioD in the asymmetric unit.|
