Abstract
The beta-lactamase from Enterobacter cloacae P99 has been crystallized from polyethylene glycol solution at pH 7. X-ray examination of the orthorhombic crystals shows the space group is P2(1)2(1)2 with unit cell dimensions a = 77.4 A, b = 69.4 A, and c = 63.6 A. There is one molecule of molecular weight 39,000 in the asymmetric unit.
摘要
阴沟肠杆菌P99的β-内酰胺酶已在pH 7的聚乙二醇溶液中结晶。对正交晶体的X射线检查表明，空间群为P2(1)2(1)2，晶胞尺寸a = 77.4 Å，b = 69.4 Å，c = 63.6 Å。不对称单元中有一个分子量为39,000的分子。
