The highest enzyme producer alkalophilic Bacillus sp SHY8-1 among the inductive strains was mutagenized several times, by adding enzyme production repression aegents into screen medium, combined with natural seperation and pressure selection, finally a CMCase-hyperproductive mutant SHY8-1-25 (partitally resistant to catabolite) was obtained, with the yield of CMCase raised to 13-16u/ml, maximally reached 18-20u/ml, while its parent strain 0.654u/ml.

I. Design and selection of thc high affinity DNA ligands for singIe-chain reprcssorSingle-chain repressor RRn., is a derivative of bacteriophage 434 repressor,which contains covalent1y dimerized DNA-binding domains (axnino acids 1-69) of thephage 434 repressor.
一。设计和筛选单链阻遏蛋白的高亲和力DNA结合序列单链阻遏蛋白RR_是噬菌体434阻遏蛋白的衍生物，它是噬菌体434阻遏蛋白的N端DBD（1—69位氨基酸）组成的共价二聚体。

The homeodomain is responsible for binding to DNA, and experiments to swap homeodomains between proteins suggest that the specificity of DNA recognition lies within the homeodomain, but (like the situation with phage repressors) no simple code relating protein and DNA sequences can be deduced.
同源域负责结合DNA，在蛋白质之间交换同源域的实验证实了这一结论。但（就像噬菌体阻遏子的情形一样）并没有推出联系蛋白质与DNA序列的简单机理。同源域的C端和原核生物阻遏子α-β-α超二级结构有一定的同源关系。我们回想第13章，λ阻遏子有一个&识别螺旋&（α-螺旋-3）DNA的大构接触，而另一个螺旋（α-螺旋-2）位于 DNA的拐角。
