CC -!- FUNCTION: DNA ligase that seals nicks in double-stranded DNA during DNA
CC replication, DNA recombination and DNA repair. Recruits cellular
CC topoisomerase II to sites of viral replication and assembly.
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + (deoxyribonucleotide)n-3'-hydroxyl + 5'-phospho-
CC (deoxyribonucleotide)m = (deoxyribonucleotide)n+m + AMP +
CC diphosphate.; EC=6.5.1.1; Evidence={ECO:0000255|PROSITE-
CC ProRule:PRU10135};
CC -!- COFACTOR:
CC Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC Evidence={ECO:0000250};
CC -!- SUBUNIT: Interacts with host TOP2A and TOP2B. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Host cytoplasm. Note=Found in sites viral of
CC replication and assembly. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the ATP-dependent DNA ligase family.
CC {ECO:0000305}.
