FunFam 1183: Terminase, 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 0 GO terms relating to "molecular function"

GO Term Annotations Evidence
Viral terminase complex GO:0043493
A complex of a large and small subunit which catalyze the packaging of DNA into viral heads. Note that not all viral terminases have this structure, some exist as single polypeptides.

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.
