The Enzymatic Methylation of Ribonucleic Acid and Deoxyribonucleic Acid. Vii. the Methylation of Ribonucleic Acid.
Preceding publications from this laboratory have shown that the methylation of soluble ribonucleic acid is catalyzed by at least six discrete enzymes (l-3) which have been purified from extracts of Escherichia coli W. Two of these enzyme preparations catalyze the formation of l-methylguanine residues in SRNA,1 while a third produces 7-methylguanine. The others catalyze the methylation of uracil...

متن کاملThe enzymatic methylation of ribonucleic acid and deoxyribonucleic acid. IX. Deoxyribonucleic acid methylase in bacteriophage-infected Escherichia coli.
Infection of Escherichia coli B with bacteriophages Tl, T2, or T4 results in increase in the activity of deoxyribonucleic acid methylase assayed in crude extracts of the infected cells. The largest increase is observed after infection with T2. phage; T4 and Tl phages lead to smaller increases in that order of decreasing magnitude. After infection with T3, T5, or T6 phages, a decrease in activit...

Triostin antibiotics, which contain a cyclic peptide with a disulphide bridge, have been prepared by growing Streptomyces triostinicus in the presence of inorganic [3PS]sulphate. The labelled triostin A has been shown to behave in all respects similarly to the authentic natural product and to enable a much more sensitive radiochemical adaptation of the solvent-partition method for determining a...

The effects of the three antibiotics U-12,241, nogalamycin, and U-20,661 on (i) deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) synthesis in KB cell cultures and cell-free systems of bacterial and mammalian origin and on (ii) oxidative phosphorylation in rat liver mitochondria were compared. Nogalamycin and U-12,241 inhibited RNA synthesis more strongly than DNA synthesis in all test sys...
