Abstract
The C-terminal DNA-binding domain of OmpR, a positive regulator involved in osmoregulation expression of the ompF and ompC genes in Escherichia coli, has a helix-turn-helix variant motif. The 'turn' region, consisting of 11 residues, forms an RNA polymerase contact site.
摘要
OmpR是一种参与大肠杆菌中ompF和ompC基因渗透调节表达的正调控因子，其C端DNA结合结构域具有一种螺旋-转角-螺旋变体基序。由11个残基组成的“转角”区域形成一个RNA聚合酶接触位点。
