利用可描述协同结合特性的动力学方法,得到了反映单个别构酶ATCase分子的结合分数与底物浓度之间的关系式.表明在确定的底物浓度条件下,单个别构酶ATCase分子处于确定的构象态,随着底物浓度的增加,别构酶ATCase分子将经历一系列中间态... 利用可描述协同结合特性的动力学方法,得到了反映单个别构酶ATCase分子的结合分数与底物浓度之间的关系式.表明在确定的底物浓度条件下,单个别构酶ATCase分子处于确定的构象态,随着底物浓度的增加,别构酶ATCase分子将经历一系列中间态达到饱和构象态,S型结合分数曲线实际上显示了单个别构酶ATCase分子与底物分子的协同结合特性.利用所得模型分析了调节物分子对底物协同结合过程的影响,合理解释了结合分数曲线随调节物浓度变化而发生改变的实验结果,与别构酶ATCase分子具有的结构及所产生的生物学功能是自给的. 展开更多

This paper discusses the present-day philosophical rupture away from identitarian thinking, and how the former has influenced the world of the feminist literary criticism of today. Herein, we embark on a journey from its awakenings back in the 1960s. We begin our quest with Kate Millett, we will continue our discussion with Irigaray, Cixous, or Kristeva and their analysis of the difference created by gender. And, we will reflect on the influence it has made to the American movement. We use the aforementioned as the lead towards the theory of deconstruction in authors such as Felman or Spivak, and how we reach the concept of performativity of gender in line with Butler and the queer theory. 展开更多
