The 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 کاملBacteriophage T7 Deoxyribonucleic acid replication in vitro. A protein of Escherichia coli required for bacteriophage T7 DNA polymerase activity.
In vivo, replication of T7 DNA does not occur after infection of Escherchia coli tsnC mutants (CHAMBERLIN, M. (1974) J. Virol. 14, 509-516). In vitro, extracts of tsnC mutant E. coli infected with T7 hage are incapable of replicating duplex T7 DNA, although extracts of wild type E. coli infected with T7 phage support replication of T7 DNA. In addition, extracts of the infected tsnC mutant are d...
متن کاملDeoxyribonucleic Acid Polymerase III of Escherichia coli
DNA polymerase III has been purified 4,500-fold from the Escherichia coli mutant, HMS83, which lacks DNA polymerases I and II. When subjected to disc gel electrophoresis, the most purified fraction exhibits a single major protein band from which enzymatic activity may be recovered. Polyacrylamide gel electrophoresis under denaturing conditions produces two protein bands with molecular weights o...
متن کاملCorrelation between degradation of bacteriophage T2 deoxyribonucleic acid and the resistance of Escherichia coli to infection.
The ability of certain strains of Escherichia coli to degrade T2 deoxyribonucleic acid to acid-soluble fragments is correlated with their high capacity to survive T2 infection.
متن کاملInfection of Bacillus stearothermophilus with bacteriophage deoxyribonucleic acid.
Early stationary-phase cells are most susceptible to infection with deoxyribonucleic acid from bacteriophage TP-1C. Transfection is destroyed by deoxyribonuclease and unaffected by phage antiserum.
