Abstract
Pertactin, a membrane-associated protein of Bordetella pertussis, has been crystallized in the presence of 28% ammonium sulphate. The space group is P6(3)22 with cell dimensions a = b = 178.2 A and c = 106.8 A. The crystals diffract to 3.3 A using a rotating anode source and are suitable for an X-ray structure determination. Assuming one molecule in the asymmetric unit, 70% of the cell is occupied by solvent.
摘要
百日咳杆菌黏附素是百日咳博德特氏菌的一种膜相关蛋白，已在28%硫酸铵存在的情况下结晶。空间群为P6(3)22，晶胞参数a = b = 178.2 Å，c = 106.8 Å。使用旋转阳极X射线源，这些晶体的衍射极限为3.3 Å，适合进行X射线结构测定。假设不对称单元中有一个分子，晶胞的70%被溶剂占据。
