  • Title: Two alternative mechanisms for initiation of DNA replication forks in bacteriophage T4: priming by RNA polymerase and by recombination.
    Author: Luder A, Mosig G.
    Journal: Proc Natl Acad Sci U S A; 1982 Feb; 79(4):1101-5. PubMed ID: 7041114.
    Abstract:
    We show that bacteriophage T4 has two alternative mechanisms to initiate DNA replication; one dependent on Escherichia coli RNA polymerase (RNA nucleotidyltransferase, EC 2.7.7.6), and one dependent on general recombination. Continued DNA synthesis under recombination-defective conditions was sensitive to rifampin, an inhibitor of RNA polymerase. On the other hand, DNA synthesis accelerated in spite of the present of rifampin if recombination occurred.
