== Function ==
[https://www.uniprot.org/uniprot/VINT_SSV1 VINT_SSV1] This protein may encode a site-specific integrase, which is necessary for integration of the phage by site-specific recombination into a tRNA gene of the host chromosome. Essential for virus infection.<ref>PMID:10430570</ref> <ref>PMID:22683788</ref>

== Publication Abstract from PubMed ==
The first structure of a catalytic domain from a hyperthermophilic archaeal viral integrase reveals a minimal fold similar to that of bacterial HP1 integrase and defines structural elements conserved across three domains of life. However, structural superposition on bacterial Holliday junction complexes and similarities in the C-terminal tail with that of eukaryotic Flp suggest that the catalytic tyrosine and an additional active-site lysine are delivered to neighboring subunits in trans. An intramolecular disulfide bond contributes significant thermostability in vitro.
