从λ阻遏物片段保护操纵基因碱基不受化学修饰的能力差异来看，我们认为λ阻遏物的前几个N-末端残基形成了一个延伸臂，当阻遏物与操纵基因结合时，延伸臂延伸到DNA螺旋的后部。
From differences in the ability of fragments of the λ repressor to protect operator bases from chemical modification we suggest that the first few N-terminal residues of the λ repressor form an extended arm that reaches around the back of the DNA helix when repressor binds to the operator.
