摘要

摘要通过分子动力学研究了模拟盒大小对溶菌酶结晶前在其溶液中形成的二聚体和六聚体稳定性的影响。模拟了这些低聚物在不同大小模拟盒中的行为，并评估了它们的稳定性。结果表明，增大模拟盒并不会导致模拟结果的细化。二聚体的稳定性微弱地依赖于盒子的大小，而六聚体在所有考虑的盒子中都会解离，这与小角散射数据一致。确定了蛋白质与方框边缘之间的最小距离（1 nm），在该距离上，结晶溶液中的低聚物行为建模结果是可靠的。

Influence of Simulation Box Sizes on the Stability of Lysozyme Dimers and Hexamers in a Crystallization Solution

The effect of the simulation box size on the stability of lysozyme dimers and hexamers formed in its solution before crystallization is studied by molecular dynamics. The behavior of these oligomers in boxes of different sizes is simulated, and their stability is assessed. It is shown that increasing the simulation box does not lead to refinement of the simulation results. The dimer stability weakly depends on the box sizes, while hexamers dissociated in all boxes considered, which is consistent with small-angle scattering data. The minimum distance between the protein and the box edge, at which the results of modeling oligomer behavior in crystallization solutions are reliable, is determined (1 nm).
