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.

Because I thought that the French were simply megalomaniacs and this whole project would probably never happen, and because I was surrounded by this rope of expectant experts, I decided to bluff and said, we know exactly how to resolve this problem: where the two lane TGV railway widens to six, we will run the highway parallel to the station. We will also run it underground, and in between, we will create the largest parking lot in the history of Christendom--8, 000 places, and in this way, an unbelievable metropolitan concentrate of infrastructure. We used this underground literally as the basis for our project.
