(Singh, 2004). The Protein Databank may also contain several structures for the same protein. In this case, all potential structures should be checked for quality and completeness to select the most suitable one for MD simulation. Once a PDB structure is downloaded, it could be checked and ...

1.9.2 蛋白质-配体相互作用能 Protein-Ligand Interaction Energy 为了量化JZ4和T4溶菌酶之间相互作用的强度,计算这两个物种之间的非键相互作用能可能是有用的。 GROMACS能够分解任意数量的已定义基团之间的短距离非结合能。重要的是要注意,该数量不是自由能或结合能。实际上,大多数力场的参数设置方式实际上并没有实...
通过energy模块提取感兴趣的能量项。我们感兴趣的是Coul-SR:Protein-JZ4和LJ-SR:Protein-JZ4。 gmx energy-f ie.edr-o interaction_energy.xvg 平均短程Coulombic相互作用能是-20.5 ± 7.4 kJ mol-1,而短程Lennard-Jones相互作用能是 -99.1 ± 7.2 kJ mol-1。我们很想从这两个数据中得出一些结论,但即使是...
