Abstract
The Escherichia coli dnaC protein is not absolutely required in vivo for bacteriophage phiX174 parental replicative-form synthesis (Kranias and Dumas, 1974). However, when rifampin is present at a concentration that inhibits DNA-dependent RNA polymerase, phiX174 parental replicative-form synthesis is dependent on the dnaC protein activity. We conclude that E. coli DNA-dependent RNA polymerase can substitute for the dnaC protein in phiX174 parental replicative-form DNA synthesis, presumably in its initiation. The implications of this result with respect to the in vitro synthesis of the complementary strand of phiX174 DNA are discussed.
