FunFam 10828: CCHC-type zinc finger protein

There are 5 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
Chitin synthase. [EC: 2.4.1.16]
UDP-N-acetyl-alpha-D-glucosamine + (1,4-(N-acetyl-beta-D- glucosaminyl))(n) = UDP + (1,4-(N-acetyl-beta-D-glucosaminyl))(n+1).
  • Converts UDP-N-acetyl-D-glucosamine into chitin and UDP.
3 A0A0L1HZG5 A0A0L1HZG5 A0A0L1HZG5
Ribonuclease H. [EC: 3.1.26.4]
Endonucleolytic cleavage to 5'-phosphomonoester.
  • Acts on RNA-DNA hybrids.
2 K0KK74 K0KM08
Polyribonucleotide nucleotidyltransferase. [EC: 2.7.7.8]
RNA(n+1) + phosphate = RNA(n) + a nucleoside diphosphate.
  • ADP, IDP, GDP, UDP and CDP can act as donors.
1 G0QN40
RNA helicase. [EC: 3.6.4.13]
ATP + H(2)O = ADP + phosphate.
  • RNA helicases utilize the energy from ATP hydrolysis to unwind RNA.
  • Some of them unwind RNA with a 3' to 5' polarity, other show 5' to 3' polarity.
  • Some helicases unwind DNA as well as RNA.
  • May be identical with EC 3.6.4.12 (DNA helicase).
1 P34689
HIV-2 retropepsin. [EC: 3.4.23.47]
Endopeptidase for which the P1 residue is preferably hydrophobic.
  • Responsible for the post-translational processing of the human immunodeficiency virus polyprotein.
  • Belongs to peptidase family A2.
