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。

So when we felt another kind of tetra-dimensional, extreme, music-like art made up of colors and lines in Malevich and Tatlin's experiment in the early of last century, people had to get used to the visional format from Kandinsky, Pollock, Mondrian and Roscoe. The brand-new artistic experiment is further rooted into experience of our religion, music, philosophy, life and other staffs not only from format to content, but also from theory to techniques. And the traditional plane paintings are used to annotate the art meaning of non-representation. But Chinese are unwilling. It is only the format product of powerful culture in expanding, rather that there are lots of differences between the western abstract and oriental "image".

所以当我们从上个世纪初在马列维奇、塔特林的实验中，体验到一种被称为四度的、极致的、音乐似的、或者说将色彩和线编制成为另一种艺术自由的端倪时，人们就不得不习惯由康定斯基、波洛克、蒙德里安和罗斯科所带给我们的视觉图式，它们从形式到内容、从理论到技巧，无不变本加厉地把这种全新的艺术实验根植于我们对宗教、音乐、哲学、生活以及诸多问题的体验中，并用传统的二维平面绘画来诠释出非具象的艺术意义，不过这些对中国人来说，很可能是不情愿的，它只是强势文化在扩张中的样式产物，更何况这些西方式的抽象与东方式的"意象"仍然有着极大的差异。
