  • Title: The organization of the right-end early region of bacteriophage PRD1 genome.
    Author: Pakula TM, Savilahti H, Bamford DH.
    Journal: Gene; 1989 Dec 21; 85(1):53-8. PubMed ID: 2695404.
    Abstract:
    Bacteriophage PRD1 is the only protein-primed DNA replication system known to operate in Escherichia coli. The left-genome end of PRD1 contains the early genes for the terminal protein and the DNA polymerase. These genes have been sequenced and the proteins have been produced separately. In this investigation we completed the analysis of the PRD1 early DNA regions by cloning and sequencing the right end genome containing early genes XII and XIX. We compared the structure of the right- and left-terminal regions. The genome organization of both ends was found to be rather uniform. The inverted terminal repeats, the first promoters and the first translation start codons are located almost exactly at the same distance from the genome ends. The PRD1 early gene products, P12 and P19, do not share similarities with proteins found in other protein-primed replication systems.
