N2 - The basic results of the studies on expression of the genes of human alpha F- and beta 1-interferons in E. coli cells are presented. To synthesize the fibroblast interferon, the respective fragment of the human chromosome was cloned, the complete nucleotide sequence of the structural moiety of mature beta-interferon was determined and the genes of "hybrid (interferon-like) proteins" and "hybrid sites of ribosome binding" were constructed with control of the beta-interferon gene by the prokaryotic regulatory areas. Synthesis of beta-interferon was achieved (1.10(7)-5.10(7) IU per 1 l of the bacterial culture) with the use of the tryptophan operon promoter. A new procedure for optimization of allogenic genetic information in E. coli cells: constructing of "hybrid operons with partially overlapping genes" or artificial "overlappons" was developed following the example of the alpha F-interferon gene cloned in the Laboratory headed by E. D. Sverdlov at the Institute of Bioorganic Chemistry of the USSR Academy of Sciences. The use of this procedure enabled production of up to 5.10(7) IU/l of alpha F-interferon under the control of the lacUV5-promoter. On the basis of the newly constructed vector molecules expression of the genes of alpha F- and beta 1-interferons was amplified with the "overlappon" procedure.
