Crystallization of and preliminary crystallographic data for the N-terminal half-molecule of ovotransferrin

The N-terminal half molecule of ovotransferrin has been crystallized from a polyethylene glycol 6000 solution by means of the vapor diffusion method. The crystals belong to the orthorhombic system, space group P2(1)2(1)2(1), with cell dimension of a = 47.0, b = 90.2, and c = 76.2 A. The crystals diffract X-rays to a resolution limit of at least 2.0 A and are resistant to X-ray radiation damage. They appear to be suitable for X-ray structure analysis.
