Abstract

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 °C. We have found that MgSO₄ and glycerol were essential for large crystal growth. The crystals belong to the orthorhombic space group P2₁2₁2, 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 Å.
