Crystallization and preliminary crystallographic analysis of D-serine dehydratase from chicken kidney

D-Serine dehydratase purified from chicken kidney was crystallized by the hanging-drop vapour-diffusion method using PEG 4000 and 2-propanol as precipitants. The crystal belonged to space group P422, with unit-cell parameters a = 105.0, c = 81.89 Å, and diffracted to 2.09 Å resolution. An attempt to solve the structure using the MAD method is in progress.
