ratio, promoting microtubule polymerization and stability. The conformation of microtubule-bound drug has been the subject of intense study, and various suggestions have been proposed. In previous work we presented experimental and theoretical evidence that paclitaxel adopts a T-shaped conformation when it is bound to tubulin. In this study we report additional experimental data and calculations that
重要的抗癌药物紫杉醇以化学计量比与微管中的字母微管蛋白二聚体的β亚基结合,从而促进微管聚合和稳定性。微管结合药物的构象一直是研究的主题,并提出了各种建议。在以前的工作中,我们提供了实验和理论证据,表明紫杉醇与微管蛋白结合时呈T形构象。在这项研究中,我们报告了其他实验数据和计算结果,这些数据和计算描述了有效的紫杉醇-微管蛋白相互作用的允许参数。
