PG - 1504-6 AB - The structural domain of the PRRSV nucleocapsid N protein was overexpressed in Escherichia coli and purified to homogeneity. Crystals of the expressed protein, designated His-Ndelta(57), were obtained by hanging-drop vapour diffusion using PEG 3350 as precipitant at pH 6.5. A native data set from a frozen crystal was collected to 2.7 A resolution using synchrotron radiation. The crystals belong to space group P3(1)21 or P3(2)21, with unit-cell parameters a = 44.41, c = 125.05, and contain a dimer in the asymmetric unit.
