Studies on the replication of bacteriophage Cp-1 DNA in Streptococcus pneumoniae.
The DNA of bacteriophage Cp-1 replicates at optimal conditions when Cp-1-infected Streptococcus pneumoniae was incubated at 30 degrees C. The in vitro formation of the initiation complex between the terminal protein and 5'-dAMP was only partially inhibited at 37 degrees C whereas an almost complete inhibition of the DNA replication was found at this temperature in vivo. Aphidicolin inhibited the multiplication of phage Cp-1 but not that of Dp-4. This drug did not affect the in vitro formation of the initiation complex but seems to affect extensive Cp-1 DNA replication in vivo.
