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.
