FunFam 21761: CP4-57-like prophage integrase IntA

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 3 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
Prophage integrase activity GO:0008979
Catalysis of the integration of prophage DNA into a target DNA molecule, usually a bacterial chromosome, via a sequence-specific recombination event which involves the formation of an intasome, a DNA-protein-complex designed for site-specific recombination of the phage and host DNA.
3 Q57497 (/ISS) Q9KR84 (/ISS) Q9KUK2 (/ISS)
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
1 P32053 (/IPI)
Prophage integrase activity GO:0008979
Catalysis of the integration of prophage DNA into a target DNA molecule, usually a bacterial chromosome, via a sequence-specific recombination event which involves the formation of an intasome, a DNA-protein-complex designed for site-specific recombination of the phage and host DNA.
1 P32053 (/IMP)

GO Term Annotations Evidence
Provirus GO:0019038
The name given to a viral genome after it has been integrated into the host genome; particularly applies to retroviruses and is a required part of the retroviral replication cycle.
