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.

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 domain is found in ATP-dependent DNA helicase RecG from bacteria the homologue from Arabidopsis, which has a critical role in recombination and DNA repair. This protein comprises three structural domains, the largest N-terminal Domain 1 which interacts with DNA junctions, and Domains 2 and 3 at the C-terminal which contain the characteristic motifs that identify RecG as an SF2 helicase. This domain represents the C-terminal of Domain 3. Around 50 residues that extend from its end cross back to Domain 1 forming a hook that wraps around the extended alpha-helix. This interaction provides a link between Domain 1 and 3 and it is likely that these residues are involved in conformational changes associated with domain movements arising from ATP binding and hydrolysis [1].
