title: [Effectiveness of expression of chloramphenicol acetyltransferase gene controlled by foreign regulatory regions in Escherichia coli. III. Relative effectiveness of cloned promoters of Escherichia coli and coliphages].
abstract: The study on the rate of initiation of model gene cat transcription under the control of E. coli (Plac UV5, Ptrp, Pcat, Ptac), phage lambda (PL, PR), phi X174 (PD) promotors was carried out by means of hybridization of pulse labelled in vivo mRNA with the DNA coding parts. The presence of gene bla(Apr) with its own constitutive promoter in all the recombinants permitted to use the level of appropriate mRNA in the cell as an internal standard. This method allowed to evaluate the true efficiency of the promoters in question. The strength of the promoters studied is shown to be equal within the limit of one order value.
