CATH Classification

Domain Context

CATH Clusters

Superfamily DEAH helicase family, winged-helix domain
Functional Family Pre-mRNA-splicing factor ATP-dependent RNA helicase

Enzyme Information

3.6.4.13
RNA helicase.
based on mapping to UniProt P53131
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).
