FunFam 1414: Terminase DNA packaging enzyme large subunit

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 1 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

GO Term Annotations Evidence
Viral terminase, large subunit GO:0098009
The part of the viral terminase complex that contains the translocase and endonuclease activities and allows the translocation of the phage DNA into the procapsid. The large subunit usually assembles as a heterooligomer with the small subunit.
