We describe methods to express the nucleoprotein (NP) of Lassa fever virus (LASV) in E. coli, to purify and crystallize it using the sitting-drop vapor diffusion method. The crystals were screened using Rigaku micro-007 X-ray generator and a dataset was collected at a resolution of 2.36 Å. The crystals belong to space group P3, with the unit cell parameters a = b = 176.35 Å, c = 56.40 Å, α = β = 90°, and γ = 120°. Using the X-ray diffraction method, we constructed a three-dimensional structure of the LASV NP that should aid in the development of novel therapeutic strategies against this virus, for which vaccine and effective treatment modalities are currently unavailable.
