Abstract
The iron-dependent superoxide dismutase from Mycobacterium tuberculosis has been crystallized by the hanging drop method. The crystals belong to the P2(1) space group and have unit cell dimensions of a = 68.5 A, b = 85.6 A, c = 66.5 A, beta = 99.8 degrees. There are four molecules per asymmetric unit which, from analysis of data to 2.5 A, appear to be related by non-crystallographic 222 symmetry.
摘要
结核分枝杆菌的铁依赖性超氧化物歧化酶已通过悬滴法结晶。晶体属于P2(1)空间群，晶胞参数为a = 68.5 Å，b = 85.6 Å，c = 66.5 Å，β = 99.8°。每个不对称单元中有四个分子，根据2.5 Å数据的分析，这些分子似乎通过非晶体学222对称性相关联。
