摘要
L-Serine dehydratase (SDH) catalyzes the pyridoxal phosphate (PLP) dependent deamination of L-serine to yield pyruvate. Recombinant human serine dehydratase was crystallized by the hanging-drop vapour-diffusion method. Crystals were grown at 291 K using (NH(4))(2)SO(4) as precipitant. Diffraction data were obtained to a resolution of 2.5 Angstrom from a single frozen crystal using Cu Kalpha radiation. The crystal belongs to space group I422, with unit-cell parameters a = 157.4, b = 157.4, c = 59.2 Angstrom, alpha = beta = gamma = 90degrees. The asymmetric unit contains one molecule and has a solvent content of about 46%.
