| Primary Identifier | IPR007502 | Type | Domain |
| Short Name | Helicase-assoc_dom |
| description | This is the helicase associated domain (HA2) found as a diverse set of RNA helicases. It has an all α-helical fold that can be divided in two subdomains, an N-terminal degenerated winged helix (WH) and a C-terminal ratchet-like domain [, , , ]. This domain collaborates with the RecA domains at the N-terminal in the formation of a RNA binding channel to allow the helicases to keep a stable grip on the RNA. |
