Crystallization of a calcium-binding EGF-like domain.
Crystals of a calcium-binding epidermal growth factor (EGF)-like domain of human clotting factor IX suitable for X-ray diffraction analysis have been obtained by vapour diffusion (sitting drop) against 48% PEG 400. The crystals belong to the tetragonal space group P4(3)2(1)2, with unit-cell dimensions a = b = 40.3, c = 98.2 A. The crystals diffract beyond 1.5 A resolution and are relatively stable in the X-ray beam. This is the first reported crystallization of a calcium-binding EGF-like domain.
