Still another change to the experimental model: a sublethal dose of E coli was administered and the animals were observed.

对实验模型还进行了另一种变化：给动物注射亚致死剂量的大肠杆菌，并进行观察。

The regulation of gene expression is to have relations to the assembly of the DNA binding proteins which bind to DNA to initiate the transcription. Some of these proteins have the ability to promote bending or looping of DNA. The FIS protein regulates gene expression in Escherichia coli by this property of bending DNA. There are many researches to discover the mechanism of FIS protein binds to DNA. However the experiment data only show the supposititious results and figure out the model of FIS-DNA complex structure. This research uses molecular dynamics simulation to compute the detail of the interaction between FIS and DNA. We observed FIS prominently affects the DNA bending by the type of local bending. Analyzing the DNA structure properties, roll and slide, also demonstrates the local bending type and region. The hydrogen bonds between FIS and DNA are analyzed to compare with the experiment data. Finally we compute the binding free energy between FIS and DNA to estimate the result of simulation and compare with the value of λ-repressor-DNA complex.

基因的表现与结合於DNA促使DNA转录作用起始的DNA结合蛋白组装有关，一些这类的蛋白质具有促使DNA扭曲或将DNA形成环状的能力，FIS蛋白质即是藉由扭曲DNA的特性调控大肠杆菌基因的表现，目前已有很多的研究发现FIS与DNA结合的机转，然而这些实验的数据仅能显示推测性的结果，进而利用这些结果推论出FIS与DNA聚合体结构的模型，本研究利用分子动态模拟的方式计算FIS与DNA交互作用的细节，我们观察到FIS主要影响DNA的扭曲方式为DNA区域扭曲的类型，并且分析DNA结构特性roll与slide也指出扭曲方式为区域扭曲与其扭曲的区域，我们也分析FIS与DNA之间的氢键，并且与实验的资料作比较，最后我们计算FIS与DNA之间的结合自由能评估模拟的结果，并且计算出的值和λ-repressor与DNA聚合体结构的实验值作比较。
