Abstract
We describe cir-lac operon fusions constructed by using phage Mu d(Apr lac). Expression of beta-galactosidase in these fusion strains is analogous to known regulatory properties of cir gene expression. It is concluded that the observed regulation by iron of the cir gene is under transcriptional control.
摘要
我们描述了利用噬菌体Mu d(Apr lac)构建的cir - lac操纵子融合体。这些融合菌株中β - 半乳糖苷酶的表达类似于cir基因表达的已知调控特性。得出的结论是，观察到的铁对cir基因的调控处于转录控制之下。
