Abstract excerpt
The primary structures of the replicative DNA polymerases (gp43s) of bacteriophage T4 and its distant phylogenetic relative RB69 are diverged, retaining only 61% identity and 74% similarity. Nevertheless, RB69 gp43 substitutes effectively for T4 gp43 in T4 DNA replication in vivo. We show here that RB69 gp43 replicates T4 genomes in vivo with a fidelity similar to that achieved by T4 gp43. Furthermore,...
