该方案描述了从锥虫培养阶段的 f1-atpase 的纯化.该程序产生了高度纯、均匀和活性的复合物, 适用于结构和酶学研究。

F1-ATPase 的纯化基于一种经典的生化方法,这证明对于我们了解其他 ATP 合成器的 ATP 生产机制至关重要。该技术的主要优点是,它产生一种高度纯净的酶,适合通过X射线晶体学或低温电子显微镜进行结构测定。虽然此协议针对 F1-ATPase 与锥形体进行分离进行了优化,但它可以适应其他来源,如组织或培养细胞,以及各种致病性蛋白酶。

这项技术可能导致新药的识别,以治疗严重的人类疾病。例如,结核分枝杆菌F-ATPase是结核病治疗的经过认证的药物靶点。为了开始协议,解冻并轻轻地重新暂停线粒体,也被称为米托皮斯特,以前通过低吨位解解从1倍10到11到2倍10到11个细胞的青霉蛋白锥虫布鲁西在5毫升的冰冷的缓冲剂 A.保持样品冷却。
