| 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).
