Crystallization and preliminary X‐ray diffraction analysis of rat autotaxin

Rat autotaxin has been cloned, expressed, purified to homogeneity and crystallized via hanging‐drop vapour diffusion using PEG 3350 as precipitant and ammonium iodide and sodium thiocyanate as salts. The crystals diffracted to a maximum resolution of 2.05 Å and belonged to space group P 1, with unit‐cell parameters a = 53.8, b = 63.3, c = 70.5 Å, α = 98.8, β = 106.2, γ = 99.8°. Preliminary X‐ray diffraction analysis indicated the presence of one molecule per asymmetric unit, with a solvent content of 47%.
