The thesis includes three parts : firstly , previous study and latest advance of molecular motor in biology are outlined , including myosin ' s and kinesin ' s construction and function , the latest advance of molecular motor in constructional biology ; secondly , the latest advance of molecular motor in physics is reviewed , including the general view of brownian motor and two examples of molecular motor , one being related to two kinds of flashing potention energy , the other being related to electronical bipole ; and finally , the model on unidirectional motion of molecular motor is in detail come up with , and especially , the interact ion between two heads is taken into account , followed by the construction of langevin equation and fokker - planck equation involved in the model . by using solutions of fokker - planck equation , unidirectional motion mechanism of molecular motor is analyzed 本文內容包括:首先綜述生物學領域分子馬達研究的最新進展,內容安排為:肌球蛋白的結構和功能,驅動蛋白的結構和功能,肌球蛋白和驅動蛋白定向運動機制的結構生物學方面的最新進展;其次綜述并分析了當前研究分子馬達定向運動機制的幾種物理模型,內容安排為:分子馬達運動的基本觀點和建構模型的一般方法,勢壘的兩態漲落誘導的分子馬達運動模型,分子馬達定向運動的偶極子模型;最后討論雙頭相互作用的分子馬達模型,內容安排為:先詳細論述模型的構建,再建立langevin方程和fokker - planck方程,接著用差分的方法求解出fokker - planck方程的解,然后分析和研究分子馬達定向運動的機制。

Polymer his - tagged peac1 - gfp efficiently activated myosin mg - atpase activity , which indicated that peacl might take part in correlative living activities in vivo . moreover , this result provided experimental proof in vitro for fusing gfp to actin isoform directly to study the dynamics of microfilaments and its regulation in vivo . we prepared rabbit anti - pea actins polyclonal antibodies using peacl as antigen which being expressed and purified from prokaryotic cells , and the antibodies possessed better immunity activity to pea actins 通過肌動蛋白體外對dnase以及肌球蛋白atpase活性影響的研究,發現單體his - taggedpeac1 - gfp能顯著抑制dnase活性,在肌動蛋白聚合條件下能有效激活肌球蛋白atpase活性,這一結果預示著peac1在體內可能參與相關的生命活動,為利用gfp直接與肌動蛋白異型體融合來研究體內微絲的動態變化及其調節提供了實驗依據。

Such filaments are usually composed of the contractile proteins actin and / or myosin , and are thought to play a role in cell motility , and perhaps also change in shape 這種絲通常由伸縮蛋白肌動蛋白和(或)肌球蛋白組成,一般而言它們在細胞運動中起一定作用,并可能改變自身的形狀。
