CC -!- FUNCTION: ATP-dependent DNA helicase and primase essential for viral
CC DNA replication and recombination. The helicase moves 5' -> 3' on the
CC lagging strand template, unwinding the DNA duplex ahead of the leading
CC strand polymerase at the replication fork and generating ssDNA for both
CC leading and lagging strand synthesis. ATP or dTTP hydrolysis propels
CC each helicase domain to translocate sequentially along DNA. Mediates
CC strand transfer when a joint molecule is available and participates in
CC recombinational DNA repair through its role in strand exchange. Primase
CC activity synthesizes short RNA primers at the sequence 5'-GTC-3' on the
CC lagging strand that the polymerase elongates using dNTPs and providing
CC the primase is still present. {ECO:0000256|HAMAP-Rule:MF_04154}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.12;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_04154};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_04154};
CC Note=Binds 2 Mg(2+), one of which is catalytic. {ECO:0000256|HAMAP-
CC Rule:MF_04154};
CC -!- SUBUNIT: Homohexamer. Assembles as a hexamer onto linear or circular
CC ssDNA in the presence of ATP or dTTP. Interacts (via C-terminus) with
CC the viral DNA polymerase that is bound to DNA; this interaction is
CC essential to initiate leading-strand DNA synthesis. The priming complex
CC consists of 2 DNA polymerases and 1 helicase-primase hexamer that
CC assemble on the DNA template. Interacts with the single-stranded DNA-
CC binding protein. Part of the replicase complex that includes the DNA
CC polymerase, the primase/helicase and the single-stranded DNA binding
CC protein. {ECO:0000256|HAMAP-Rule:MF_04154}.
CC -!- DOMAIN: The N-terminus zinc finger domain is essential for delivering
CC the primed DNA template to the DNA polymerase. The central core domain
CC contains the primase activity. The C-terminus region is responsible for
CC the helicase activity and binds 1 Mg(2+)-dTTP. {ECO:0000256|HAMAP-
CC Rule:MF_04154}.
CC -!- SIMILARITY: Belongs to the Teseptimavirus DNA helicase/primase family.
CC {ECO:0000256|HAMAP-Rule:MF_04154}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_04154}.
