Temperature-shift experiments with an Escherichia coli dnaG strain indicate a requirement for the dnaG function for M13 phage production only at an early stage of infection. Mutant cells infected at nonpermissive temperature form the parental RF (SS leads to RF) but do not replicate further. A shift to nonpermissive temperature after infection inhibits RF leads to RF replication but not RF leads to SS synthesis. The synthesis of both strands of the duplex RF was inhibited equally after a temperature shift during RF leads to RF replication. We infer that the dnaG protein is required for M13 production only during RF replication and that it is required for the synthesis of both strands of the RF.
