阻遏物

近年来，一些不依赖于转录因子活性的新型双杂交系统相继建立，如分离的泛素系统、蛋白质片段互补分析、阻遏物重构分析和SOS恢复系统等。

Some new type of two-hybrid systems , such as split-ubiquitin system , protein-fragment complementation assay , repressor reconstitution assay and SOS recruitment system , have been developed recently .

这也表明RecA蛋白可能在其它激活信号的激活下也可以与λCI阻遏物发生作用，而不是仅仅受ssDNA的激活。

It also indicates that the RecA protein could interact with the λ CI repressor without any activating signals , or by the activation of other signals , not only the ssDNA .
