Abstract
The potentially structured core domain of the intrinsically disordered protein Knr4 from Saccharomyces cerevisiae, comprising residues 80-340, was expressed in Escherichia coli and crystallized using the hanging-drop vapour-diffusion method. Selenomethionine-containing (SeMet) protein was also purified and crystallized. Crystals of both proteins belonged to space group P6522, with unit-cell parameters a = b = 112.44, c = 265.21 Å for the native protein and a=b=112.49, c = 262.21 Å for the SeMet protein, and diffracted to 3.50 and 3.60 Å resolution, respectively. There are two molecules in the asymmetric unit related by a twofold axis. The anomalous signal of selenium was recorded and yielded an electron-density map of sufficient quality to allow the identification of secondary-structure elements.
