Abstract

The (R)-selective amine transaminase from Aspergillus fumigatus was expressed in Escherichia coli and purified to homogeneity. Bright yellow crystals appeared while storing the concentrated solution in the refrigerator and belonged to space group C222(1). X-ray diffraction data were collected to 1.27 Å resolution, as well as an anomalous data set to 1.84 Å resolution that was suitable for S-SAD phasing.

摘要

来自烟曲霉的(R)-选择性胺转氨酶在大肠杆菌中表达并纯化至同质。将浓缩溶液储存在冰箱中时出现亮黄色晶体,其属于空间群C222(1)。收集了分辨率为1.27 Å的X射线衍射数据,以及分辨率为1.84 Å的反常数据集,该反常数据集适用于单波长反常散射(S-SAD)相位分析。
