Crystallization and preliminary X-ray crystallographic analysis of a yedU gene product from Escherichia coli

A yedU gene product with a molecular mass of 31 kDa is a hypothetical protein with no known function. The protein was purified and crystallized at 296 K. X-ray diffraction data have been collected to 2.3 Å using synchrotron radiation. The crystals belong to the primitive orthorhombic system, with unit-cell parameters a = 50.56, b = 63.45, c = 168.02 Å. The asymmetric unit contains two monomers of the protein, with a corresponding V_M of 2.25 ų Da⁻¹ and a solvent content of 44.84%.
