| PF00270 | DEAD/DEAH box helicase (DEAD) | DEAD/DEAH box helicase | 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 ... | Domain | |
| 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 | |
| PF16124 | RecQ zinc-binding (RecQ_Zn_bind) | RecQ zinc-binding | This domain is the zinc-binding domain of ATP-dependent DNA helicase RecQ [1-2]. | Domain |
