[Synthesis of aminoglycoside phosphotransferase is under control the PL-promoter of phage lambda].
The recombinant plasmid pKP145 PL has been constructed containing the gene for aminoglycosidephosphotransferase (APT). Expression of the APT gene is under the control of lambda bacteriophage PL promoter. Escherichia coli cells harbouring this plasmid synthesize APT in quantity up to 13-15% of the total cellular protein. The technique for isolation of APT from superproducing cells has been elaborated. Preparations of the enzyme devoid of contaminating bacterial proteins have been obtained.
