将非天然氨基酸安装到活细胞的蛋白质中是一项促进大量应用的技术。UV可活化的交联剂氨基酸允许在活细胞中的相互作用伴侣之间形成共价键,具有近乎完美的空间和时间控制。在这里,我们描述了如何可以采用这种方法来映射染色质相互作用,并遵循这些相互作用在同步酵母菌群的细胞周期。因此,这种方法提供了前所未有的见解的分子事件控制染色质重组有丝分裂。由于类似的工具可用于其他生物体,因此应该可以为这些和其他同步过程推导出类似的策略。
The installation of unnatural amino acids into proteins of living cells is an enabling technology that facilitates an enormous number of applications. UV-activatable crosslinker amino acids allow the formation of a covalent bond between interaction partners in living cells with nearly perfect spatial and temporal control. Here, we describe how this method can be employed to map chromatin interactions and to follow these interactions across the cell cycle in synchronized yeast populations. This method thereby provides unprecedented insights into the molecular events controlling chromatin reorganization in mitosis. As similar tools are available for other organisms, it should be possible to derive similar strategies for these and for other synchronizable processes.
