FunFam 632927: ATP-dependent RNA helicase DDX50

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 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.
 1 A0A0B2S1U7
Cystathionine gamma-synthase. [EC: 2.5.1.48]
O(4)-succinyl-L-homoserine + L-cysteine = L-cystathionine + succinate.
  • Also reacts with H(2)S and methanethiol as replacing agents, producing homocysteine and methionine, respectively.
  • In the absence of thiol, can also catalyze beta,gamma-elimination to form 2-oxobutanoate, succinate and ammonia.
  • Formerly EC 4.2.99.9.
