Human semicarbazide-sensitive amine oxidase (SSAO) is a homodimeric copper-containing monoamine oxidase that occurs in both a membrane-bound and a soluble form. SSAO is also known as vascular adhesion protein-1 (VAP-1). A truncated soluble form of human SSAO (comprising residues 29-763) was expressed in human embryonic kidney 293 cells and purified to homogeneity. Tetragonal crystals were obtained and a data set extending to 2.5 A was collected. The crystals are merohedrally twinned and the estimation of the twinning fraction was complicated by pseudo-symmetry and the anisotropic character of the crystals. Using a recently developed method for twinning detection that is insensitive to phenomena such as anisotropy or pseudo-symmetry [Padilla & Yeates (2003), Acta Cryst. D59, 1124-1130], the twinning fraction was estimated to be 0.3. The structure was eventually solved by molecular replacement in space group P4(3).
