Gamma-irrdiation of E. coli MRE 600 ribosomes in aqueous suspensions leads to covalent linkages between the RNA and some ribosomal proteins. The presence of oxygen during the irradiation strongly inhibits this phenomenon. It appears clearly that only

When dibenzo[a,e]fluoranthene (DBF) is incubated in vitro with mouse liver microsomes in the presence of calf thymus DNA, several metabolites bind covalently to DNA. The metabolite-nucleoside adducts were separated by h.p.l.c. after enzymatic hydroly

Dibenzo[ a , e ]fluoranthene (DBF), a non-alternant carcinogenic polycyclic aromatic hydrocarbon (PAH), binds covalently to DNA. The main adducts were characterized as covalent additions of its bay-region and pseudo-bay-region diol-epoxides. The stru

SummaryIrradiation in vitro of 30S and 50S ribosomal subunits from E. coli MRE 600 by gamma rays from cobalt 60, in the absence of oxygen, results in the formation of covalent links between the RNAs and some ribosomal proteins. At low radiation doses

Using the “melting curve” technique, we have been able to demonstrate partial denaturation of the secondary structure of irradiated poly-(A + U): γ rays, 3.5 · 10−4 M nucleotides. The Tm decreases rapidly as the dose of radiation increases. T

The induction of RNA-protein crosslinks in E. coli 70S ribosomes by gamma-irradiation was studied by measuring the dependence of cross-link formation on ribosome concentration. The inverse dependence of cross-link percentage upon concentration up to
