CC -!- FUNCTION: Type II topoisomerase. Processively relaxes supercoiled DNA.
CC Displays DNA-supercoiling activity only when associated with the viral
CC histone-like protein. {ECO:0000250|UniProtKB:Q00942}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP-dependent breakage, passage and rejoining of double-
CC stranded DNA.; EC=5.6.2.2; Evidence={ECO:0000250|UniProtKB:Q00942};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:P11388};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000250|UniProtKB:P11388};
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108;
CC Evidence={ECO:0000250|UniProtKB:P11388};
CC Note=Binds two Mg(2+) per subunit. The magnesium ions form salt bridges
CC with both the protein and the DNA. Can also accept other divalent metal
CC cations, such as Mn(2+) or Ca(2+). {ECO:0000250|UniProtKB:P11388};
CC -!- SUBCELLULAR LOCATION: Host cytoplasm {ECO:0000250|UniProtKB:Q00942}.
CC Note=Localizes to the cytoplasmic viral factories.
CC {ECO:0000250|UniProtKB:Q00942}.
CC -!- INDUCTION: Expressed in the early phase of the viral replicative cycle.
CC {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the type II topoisomerase family. {ECO:0000305}.
