Domain Context

CATH Clusters

Superfamily	C2 domain
Functional Family	Small nuclear ribonucleoprotein 200kDa

Enzyme Information

3.6.4.13

RNA helicase.

based on mapping to UniProt O75643

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).
