Abstract
The 3-A structure of DNA-binding protein II, which exhibits histone-like properties in bacteria, has been determined. The molecule is dimeric and appears to bind to the phosphate backbone of DNA through two symmetry-related arms. A mechanism by which the protein induces DNA supercoiling is proposed.
摘要
已确定在细菌中表现出组蛋白样特性的DNA结合蛋白II的3-A结构。该分子是二聚体，似乎通过两条对称相关的臂与DNA的磷酸主链结合。提出了一种该蛋白质诱导DNA超螺旋的机制。
