摘要
通过分子置换法测定了来自高嗜酸地杆菌（Geobacillus kaustophilus）的保守假定蛋白质 GK0453 的晶体结构，分辨率为 2.2 Å。该晶体属于空间群 P4(3)2(1)2，单位晶胞参数为 a = b = 75.69，c = 64.18 Å。该结构是通过分子置换法测定的，其最终 R 因子为 22.6%（R(free) = 26.3%）。根据结构同源性，GK0453 蛋白具有两个独立的结合位点，因此它可能同时与两种蛋白质或一种蛋白质和一种核酸相互作用。
Structure of the hypothetical DUF1811-family protein GK0453 from Geobacillus kaustophilus HTA426.
The crystal structure of a conserved hypothetical protein, GK0453, from Geobacillus kaustophilus has been determined to 2.2 Å resolution. The crystal belonged to space group P4(3)2(1)2, with unit-cell parameters a = b = 75.69, c = 64.18 Å. The structure was determined by the molecular-replacement method and was refined to a final R factor of 22.6% (R(free) = 26.3%). Based on structural homology, the GK0453 protein possesses two independent binding sites and hence it may simultaneously interact with two proteins or with a protein and a nucleic acid.
