The important anticancer drug Taxol (paclitaxel) binds to tubulin in a stoichiometric ratio and promotes its assembly into microtubules. The conformation of microtubule-bound drug has been the subject of intense study, and various suggestions have been made. In this work we present experimental and theoretical evidence that Taxol adopts a T-shaped conformation when it is bound to tubulin.
重要的抗癌药物紫杉醇(paclitaxel)以化学计量比与微管蛋白结合,并促进其组装成微管。与微管结合的药物的构象一直是深入研究的主题,并且已经提出了各种建议。在这项工作中,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。
