[The action of tomicide on macromolecular synthesis in bacterial cells].

The study of the rate of incorporation of labeled precursors for nucleic acids and protein into Staphylococcus aureus 209 P cell fraction, insoluble in trichloroacetic acid, has revealed that in the presence of tomicide in the medium in a dose of 1 MCI (600 micrograms/ml) the synthesis of DNA in inhibited rapidly and almost completely (by 90%). The inhibition of the rate of incorporation of 3H-thymidine into the cells of staphylococcal culture by tomicide directly correlates with the concentration of the preparation within the range 100-600 micrograms/ml, the inhibition of the synthesis of RNA and protein being less pronounced than the inhibition of the synthesis of DNA.
