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...

متن کاملAlkylation by propylene oxide of deoxyribonucleic acid, adenine, guanosine and deoxyguanylic acid.
1. Propylene oxide reacts with DNA in aqueous buffer solution at about neutral pH to yield two principal products, identified as 7-(2-hydroxypropyl)guanine and 3-(2-hydroxypropyl)adenine, which hydrolyse out of the alkylated DNA at neutral pH values at 37 degrees C. 2. These products were obtained in quantity by reactions between propylene oxide and guanosine or adenine respectively. 3. The rea...
متن کاملDeoxyribonucleic acid-deoxyribonucleic acid hybridization assay for replication origin deoxyribonucleic acid of Escherichia coli.
Deoxyribonucleic acid (DNA)-DNA hybridization on nitrocellulose filters can be used to assay for replication origin DNA from Escherichia coli if the DNA attached to the filters is enriched for the replication origin sequences. Such DNA can be readily isolated from very rapidly growing cells. When low amounts of this DNA were attached to filters, radioactively labeled DNA from the replication or...
