SpletIn this case, the residues will be examined in the order that they appear in the PDB file, and every atom falling between 1000 and 17J in chain A will be included. This is the only situation where the ordering of atoms is important in atom selections. B-factors and occupancies. You may also select atoms based on their numerical properties: Splet7. Writing coordinates ¶. MDAnalysis also supports writing of data in a range of file formats (see the Table of supported coordinate formats for details). MDAnalysis supports both single frame writers (such as a simple PDB or GRO file) and trajectory writers (e.g. XTC, DCD, but also multi-frame PDB files). 7.1.

SpletB-factor反映蛋白质的柔性 B 因子体现了晶体中原子电子密度的 “模糊度” (diffusion) , 这个“模糊度”实际上反映了蛋白质分子在晶体中的构象状态。 B 因子越高,“模糊度”越大,相应部位的构象就越不稳定（柔性越大）。 在晶体学数据中, B 因子一般是以原子为单位给出的,我们可以换算成相应残基的B 因子,从而分析残基的构象稳定性。 另外,计算出的B 因子中实际上包含 … Splet通常情况下，一个蛋白质所包含的信息是非常多的，与结构相关的包括：包括链名、氨基酸残基序列、原子坐标等。. 一个蛋白质的结构相关的信息可以以pdb文件的形式保存，这些文件可以直接从PDB、NCBI等数据库获取，也可以利用biopython获取。. 获取某个蛋白的 ...
