FunFam 623128: ATP-dependent RNA helicase SUB2

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
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).

Adenosinetriphosphatase. [EC: 3.6.1.3]
ATP + H(2)O = ADP + phosphate.
  • Many enzymes previously listed under this number are now listed separately as EC 3.6.1.32 to EC 3.6.1.39.
  • The remaining enzymes, not separately listed on the basis of some function coupled with hydrolyzes of ATP, include enzymes dependent on Ca(2+), Mg(2+), anions, H(+) or DNA.
  • Formerly EC 3.6.1.4.
2 A7AVP6 M9PC90
Glycine dehydrogenase (aminomethyl-transferring). [EC: 1.4.4.2]
Glycine + [glycine-cleavage complex H protein]-N(6)-lipoyl-L-lysine = [glycine-cleavage complex H protein]-S-aminomethyl-N(6)-dihydrolipoyl-L- lysine + CO(2).
  • A component of the glycine cleavage system, which is composed of four components that only loosely associate: the P protein (EC 1.4.4.2), the T protein (EC 2.1.2.10), the L protein (EC 1.8.1.4) and the lipoyl-bearing H protein.
  • Previously known as glycine synthase.
1 A0A075B017
Proteasome endopeptidase complex. [EC: 3.4.25.1]
Cleavage of peptide bonds with very broad specificity.
  • A 20-S protein composed of 28 subunits arranged in four rings of seven.
  • The outer rings are composed of alpha subunits, but the beta subunits forming the inner rings are responsible for peptidase activity.
  • In eukaryotic organisms there are up to seven different types of beta subunits, three of which may carry the N-terminal threonine residues that are the nucleophiles in catalysis, and show different specificities.
  • The molecule is barrel-shaped, and the active sites are on the inner surfaces.
  • Terminal apertures restrict access of substrates to the active sites.
  • Inhibited by mercurial reagents and some inhibitors of serine endopeptidases.
  • Belongs to peptidase family T1.
  • Formerly EC 3.4.22.21, EC 3.4.24.5 and EC 3.4.99.46.
