An auto-inhibited fragment of twitchin kinase (residues 5890 to 6262) has been crystallized by vapor diffusion techniques using polyethylene glycol 4000 as the precipitant at pH 7.25 to 7.5 at 4 degrees C. We have found that MgSO4 and glycerol were essential for large crystal growth. The crystals belong to the orthorhombic space group P2(1)2(1)2, with unit cell dimensions of a = 144.1 A, b = 168.3 A and c = 60.6 A. They are suitable for X-ray analysis and diffract to a resolution of at least 2.8 A.
