This family represents the large subunit, DP2, of a two subunit novel archaebacterial replicative DNA polymerase first characterised for <taxon tax_id="2261">Pyrococcus furiosus</taxon>. The structure of DP2 appears to be organised as a ~950 residue component separated from a ~300 residue component by a ~150 residue intein. The other subunit, DP1, has sequence similarity to the eukaryotic DNA polymerase delta small subunit. DNA polymerase II large subunit DP2
