Crystallization of thermitase, a thermostable subtilisin, from a sodium formate solution by means of an automated procedure

Abstract

A new crystal form of native thermitase has been obtained using sodium formate as the precipitating agent and employing an automated crystallization procedure. The crystals have the form of tetragonal bipyramids, the longest dimension being about 0.4 mm. The space group is and . The crystals diffract beyond 2.5
