FunFam 2: Genome polyprotein

There are 4 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
Nucleoside-triphosphate phosphatase. [EC: 3.6.1.15]
NTP + H(2)O = NDP + phosphate.
  • The enzyme is found in eukaryotes and thermophilic bacteria, but appears to be absent from mesophilic bacteria.
  • Also hydrolyzes nucleoside diphosphates, thiamine diphosphate and FAD.
  • The enzyme from the plant Pisum sativum (garden pea) is regulated by calmodulin.

RNA-directed RNA polymerase. [EC: 2.7.7.48]
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1).
  • Catalyzes RNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time.
  • Can initiate a chain de novo.
  • See also EC 2.7.7.6.

Picornain 3C. [EC: 3.4.22.28]
Selective cleavage of Gln-|-Gly bond in the poliovirus polyprotein. In other picornavirus reactions Glu may be substituted for Gln, and Ser or Thr for Gly.
  • From entero-, rhino-, aphto- and cardioviruses.
  • Larger than the homologous virus picornain 2A.
  • Belongs to peptidase family C3.

Picornain 2A. [EC: 3.4.22.29]
Selective cleavage of Tyr-|-Gly bond in the picornavirus polyprotein.
  • From entero- and rhinoviruses.
  • Smaller than the homologous virus picornain 3C.
  • Belongs to peptidase family C3.
