[Luminescent bacteria--producers of specific restriction endonucleases].

Luminescent bacteria isolated from the waters of the Black Sea and of the Indian and Pacific Oceans were tested for the presence of restriction endonucleases. For 12 of 19 restriction enzyme producers revealed, restriction sites were determined. The enzymes were identified as isoschizomers of AfIII, BanI, HaeIII, PstI, Sau3AI, and Sau96I. Possible participation of the restriction and modification enzymes in the interaction of bacterial symbionts with the animal macrosymbiont is discussed.

[Biosynthesis of alpha2-interferon and tumor necrosis factor at different stages of culturing].

Study of the biosynthesis of human alpha 2-interferon and tumor necrosis factor in derivatives of E. coli SG200-50 recipient strain containing pIF16, pTNF311, and pLT21 plasmids demonstrated elimination of the plasmids from the cells without degradation thereof in the course of culturing. Methods increasing the content of the end products in the biomass are proposed.
