染色质重塑是由Snf2家族ATPase驱动的依赖于ATP的核小体组织的改变。这一过程的生物化学依赖于ATP依赖的马达蛋白及其动态核小体底物的行为,这带来了重大的技术和概念挑战。在表征这些酶所组成的多肽方面已经取得了稳步的进展。不同亚家族Snf2相关蛋白序列的差异表明,这些马达适应不同的功能。最近的结构研究表明,Snf2 ATPase是一种上下文敏感的DNA转位酶。这可能是作为一种能够在高密度真核细胞中有效获取DNA的手段而出现的。这些酶如何与核小体接触,以及核小体内的非共价相互作用网络如何对所施加的力做出反应,目前尚不清楚,因此仍需谨慎地认识到潜在的DNA扭曲和潜在的组蛋白八聚体结构内的动力学。
Chromatin remodelling is the ATP-dependent change in nucleosome organisation driven by Snf2 family ATPases. The biochemistry of this process depends on the behaviours of ATP dependent motor proteins and their dynamic nucleosome substrates, which brings significant technical and conceptual challenges. Steady progress has been made in characterizing the polypeptides that these enzymes are comprised of. Divergence in the sequences of different subfamilies of Snf2 related proteins suggests that the motors are adapted for different functions. Recently structural insights have suggested that the Snf2 ATPase acts as a context-sensitive DNA translocase. This may have arisen as a means to enable efficient access to DNA in the high density of the eukaryotic nucleus. How the enzymes engage nucleosomes and how the network of non-covalent interactions within the nucleosome respond to the force applied remains unclear, and it remains prudent to recognise the potential for both DNA distortions and dynamics within the underlying histone octamer structure.
