[Transposition of the deo operon structural genes in Escherichia coli K-12 to plasmid RP4 using bacteriophage mu].
Transposition of the structural genes of the deo operon of Escherichia coli K-12 into plasmid RP4 by means of temperate bacteriophage Mu was carried out. Some variants of composite RP4-deo-Mu plasmids were obtained and the expression of the deo genes integrated into the RP4 plasmid genome was studied. It was shown that the expression of these genes remains under the control of the chromosomal regulatory genes (deoR and cytR); although the activity of thymidine phosphorilase in the strain E. coli which contains hybrid plasmid is 4-6 fold greater than that in strains of E. coli with chromosomal localization of the deo operon.
