Abstract
Crystals of porcine synovial collagenase suitable for an X-ray structure analysis have been obtained. The crystals belong to space group I4, with unit cell dimensions a = b = 160.0 A, c = 53.1 A, with one molecule in the asymmetric unit. Diffraction extends beyond 3 A perpendicular to the c axis but along the 4-fold axis, the intensities are measurable only to 4 A.
摘要
已获得适合进行X射线结构分析的猪滑膜胶原酶晶体。这些晶体属于空间群I4，晶胞参数为a = b = 160.0 Å，c = 53.1 Å，不对称单元中有一个分子。垂直于c轴方向衍射延伸至3 Å以外，但沿四重轴方向，强度仅在4 Å处可测量。
