FunFam 8: Gag polyprotein

There are 3 EC terms in this cluster

Please note: EC 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.

Note: 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.

EC Term Annotations Evidence
RNA-directed DNA polymerase. [EC: 2.7.7.49]
Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).
  • Catalyzes RNA-template-directed extension of the 3'-end of a DNA strand by one deoxynucleotide at a time.
  • Cannot initiate a chain de novo.
  • Requires a RNA or DNA primer.
  • DNA can also serve as template.
  • See also EC 2.7.7.7.

DNA-directed DNA polymerase. [EC: 2.7.7.7]
Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).
  • Catalyzes DNA-template-directed extension of the 3'-end of a DNA strand by one nucleotide at a time.
  • Cannot initiate a chain de novo.
  • Requires a primer which may be DNA or RNA.
  • See also EC 2.7.7.49.

Ribonuclease H. [EC: 3.1.26.4]
Endonucleolytic cleavage to 5'-phosphomonoester.
  • Acts on RNA-DNA hybrids.
