Xylanase B from Clostridium cellulovorans 743B: overexpression, purification, crystallization and X-ray diffraction analysis

In this study, XynB was cloned, overexpressed, purified and crystallized. XynB was crystallized using the hanging-drop vapour-diffusion method in the presence of 0.2   M sodium acetate trihydrate, 0.1   M Tris – HCl pH 8.5, 32%(w/v) PEG 4000 at 293   K. X-ray diffraction analysis revealed that the crystal diffracted to 1.95   Å resolution and belonged to space group P212121, with unit-cell parameters a   =   74.28, b = 77.55, c = 88.20   Å , α = β = γ = 90 ° . The data-evaluation statistics revealed high quality of the collected data, thereby establishing a solid basis for determination of the structure of cellulosomal xylanase from C. cellulovorans.
