CATH Clusters
| Superfamily | P-loop containing nucleotide triphosphate hydrolases | 
| Functional Family | DEAD-box ATP-dependent RNA helicase | 
Enzyme Information
| 3.6.4.13 | RNA helicase. based on mapping to UniProt Q13838 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). |
