Members of this family include the DEAD and DEAH box helicases. Helicases are involved in unwinding nucleic acids. The DEAD box helicases are involved in various aspects of RNA metabolism, including nuclear transcription, pre mRNA splicing, ribosome biogenesis, nucleocytoplasmic transport, translation, RNA decay and organellar gene expression.	Domain
A	PF00271	Helicase conserved C-terminal domain (Helicase_C)	Helicase conserved C-terminal domain	The Prosite family is restricted to DEAD/H helicases, whereas this domain family is found in a wide variety of helicases and helicase related proteins. It may be that this is not an autonomously folding unit, but an integral part of the helicase.	Domain

This entry includes archaeal helicases from the helicase superfamily 2, and represents domain 4 described in [1,3]. This domain folds into a seven alpha-helix bundle structure and seems to be unique within this helicase family. The central helix acts as a ratchet and mediates stacking interactions on base moieties of the DNA [3].	Domain
