CC   -!- FUNCTION: Replicates viral genomic DNA in the late phase of lytic
CC       infection, producing long concatemeric DNA. The replication complex is
CC       composed of six viral proteins: the DNA polymerase, processivity
CC       factor, primase, primase-associated factor, helicase, and ssDNA-binding
CC       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-COMP:17339,
CC         Rhea:RHEA-COMP:17340, ChEBI:CHEBI:33019, ChEBI:CHEBI:61560,
CC         ChEBI:CHEBI:173112; EC=2.7.7.7;
CC   -!- SUBUNIT: Forms a complex with the major DNA-binding protein BALF2, the
CC       DNA polymerase processivity factor BMRF1, and the alkaline exonuclease
CC       BGLF5. Interacts with the putative helicase-primase complex composed of
CC       BBLF4, BSLF1 and BBLF2/3 proteins; these interactions may coordinate
CC       leading and lagging strand DNA synthesis at the replication fork (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Host nucleus. Note=the protein is present at
CC       discrete sites in nuclei, called replication compartments where viral
CC       DNA replication occurs. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the DNA polymerase type-B family. {ECO:0000305}.
