组蛋白受到一系列翻译后修饰(PTM)的影响,这些修饰可以调节染色质的结构和功能。这种控制是通过直接改变染色质纤维的固有物理性质或通过调节一系列反式作用核因子的招募和活性来实现的。组蛋白PTM的绝对数量为理解真核基因组表观遗传调控的核心分子机制提供了强大的障碍。这个多种多样的问题的一个方面,即如何获得用于生化研究的均匀修饰的染色质,非常适合有机化学家的敏感性。事实上,近年来,合成蛋白质化学方法在产生研究组蛋白PTMS如何调节染色质生物化学所需的原材料方面发挥了关键作用。这篇综述集中在这些化学策略中最有效和被广泛使用的策略,即通过多肽片段的化学连接进行组蛋白半合成。
Histone proteins are subject to a host of posttranslational modifications (PTMs) that modulate chromatin structure and function. Such control is achieved by the direct alteration of the intrinsic physical properties of the chromatin fiber or by regulating the recruitment and activity of a host of trans-acting nuclear factors. The sheer number of histone PTMs presents a formidable barrier to understanding the molecular mechanisms at the heart of epigenetic regulation of eukaryotic genomes. One aspect of this multifarious problem, namely how to access homogeneously modified chromatin for biochemical studies, is well suited to the sensibilities of the organic chemist. Indeed, recent years have witnessed a critical role for synthetic protein chemistry methods in generating the raw materials needed for studying how histone PTMs regulate chromatin biochemistry. This review focuses on what is arguably the most powerful, and widely employed, of these chemical strategies, namely histone semisynthesis via the chemical ligation of peptide fragments.
