The Essential Role of the 3′ Terminal Template Base in the First Steps of Protein-Primed DNA Replication

Bacteriophages φ29 and Nf from Bacillus subtilis start replication of their linear genomes at both ends using a protein-primed mechanism by means of which the DNA polymerase initiates replication by adding dAMP to the terminal protein, this insertion being directed by the second and third 3′ terminal thymine of the template strand, respectively. In this work, we have obtained...

Involvement of phage ϕ29 DNA polymerase and terminal protein subdomains in conferring specificity during initiation of protein-primed DNA replication

To initiate ϕ29 DNA replication, the DNA polymerase has to form a complex with the homologous primer terminal protein (TP) that further recognizes the replication origins of the homologous TP-DNA placed at both ends of the linear genome. By means of chimerical proteins, constructed by swapping the priming domain of the related ϕ29 and GA-1 TPs, we show that DNA polymerase can...
