Operon fusions of the lacZ gene to two different genes of the cysteine regulon controlled by the cysB regulatory protein were isolated. The fusion strains were used for selection of cysB constitutive mutants. Three cysBc alleles have been characterized and cloned into multicopy plasmids.
分离出了将lacZ基因与由cysB调节蛋白控制的半胱氨酸调节子的两个不同基因的操纵子融合体。融合菌株用于筛选cysB组成型突变体。已经鉴定出三个cysBc等位基因并将其克隆到多拷贝质粒中。
