[Colicin El synthesis in a cell-free system of paired transcription--translation].

Proteins were synthesized in the cell-free coupled transcription-translation systen (S30) under the control of the DNA-templates of plasmid ColEl, phages T2 and Sd. The most active templates were phage T2 DNA and closed plasmid DNA. Plasmid DNA induced synthesis of 8 individual proteins, one of which was a biologically active antibiotic of protein nature--colicin.
