摘要

在本期的《结构》杂志上，Viennet等人报道了一项研究，描述了转录因子BCL11A的三锌指片段与DNA的结合，其不寻常的特征是游离蛋白中的指间相互作用在结合过程中被破坏，这提供了一个正熵贡献，增强了亲和力。

A finger that gets in the way: When binding isn’t just about the bound state

In this issue of Structure, Viennet et al.¹ report a study characterizing the DNA binding by a three-zinc-finger fragment from the transcription factor BCL11A, with the unusual feature that an interfinger interaction in the free protein is disrupted during binding, which provides a positive entropic contribution that enhances the affinity.

期刊介绍： Structure aims to publish papers of exceptional interest in the field of structural biology. The journal strives to be essential reading for structural biologists, as well as biologists and biochemists that are interested in macromolecular structure and function. Structure strongly encourages the submission of manuscripts that present structural and molecular insights into biological function and mechanism. Other reports that address fundamental questions in structural biology, such as structure-based examinations of protein evolution, folding, and/or design, will also be considered. We will consider the application of any method, experimental or computational, at high or low resolution, to conduct structural investigations, as long as the method is appropriate for the biological, functional, and mechanistic question(s) being addressed. Likewise, reports describing single-molecule analysis of biological mechanisms are welcome. In general, the editors encourage submission of experimental structural studies that are enriched by an analysis of structure-activity relationships and will not consider studies that solely report structural information unless the structure or analysis is of exceptional and broad interest. Studies reporting only homology models, de novo models, or molecular dynamics simulations are also discouraged unless the models are informed by or validated by novel experimental data; rationalization of a large body of existing experimental evidence and making testable predictions based on a model or simulation is often not considered sufficient.
