CC -!- FUNCTION: Replicates viral genomic DNA in the late phase of lytic CC infection, producing long concatemeric DNA. The replication CC complex is composed of six viral proteins: the DNA polymerase, CC processivity factor, primase, primase-associated factor, helicase, CC and ssDNA-binding protein (By similarity). {ECO:0000250}. CC -!- CATALYTIC ACTIVITY: CC Reaction=a 2'-deoxyribonucleoside 5'-triphosphate + DNA(n) = CC diphosphate + DNA(n+1); Xref=Rhea:RHEA:22508, Rhea:RHEA- CC COMP:11130, Rhea:RHEA-COMP:11131, ChEBI:CHEBI:33019, CC ChEBI:CHEBI:61560, ChEBI:CHEBI:83828; EC=2.7.7.7; CC -!- SUBUNIT: Forms a complex with the ssDNA-binding protein UL57, the CC DNA polymerase processivity factor UL44, and the alkaline CC exonuclease UL98. Interacts with the putative helicase-primase CC complex composed of UL70, UL102 and UL105 proteins; these CC interactions may coordinate leading and lagging strand DNA CC synthesis at the replication fork (By similarity). {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Host nucleus {ECO:0000250}. Note=the protein CC is present at discrete sites in nuclei, called replication CC compartments where viral DNA replication occurs. {ECO:0000250}. CC -!- SIMILARITY: Belongs to the DNA polymerase type-B family. CC {ECO:0000305}.
