A, B [auth C], C [auth E], D [auth G] | PF04408 | Helicase associated domain (HA2), winged-helix (HA2_N) | Helicase associated domain (HA2), winged-helix | The helicase associated domain (HA2) has an all alpha-helical fold and consists of a N-terminal winged-helix (WH) domain and a C-terminal degenerate helical-bundle domain, referred to as the ratchet-like domain [1,2,3]. These domains collaborate wit ... | Domain |
A, B [auth C], C [auth E], D [auth G] | PF07717 | Oligonucleotide/oligosaccharide-binding (OB)-fold (OB_NTP_bind) | Oligonucleotide/oligosaccharide-binding (OB)-fold | This family is found towards the C-terminus of the DEAD-box helicases (Pfam:PF00270). In these helicases it is apparently always found in association with Pfam:PF04408. There do seem to be a couple of instances where it occurs by itself - e.g. Swiss: ... | Domain |
A, B [auth C], C [auth E], D [auth G] | 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 |
A, B [auth C], C [auth E], D [auth G] | 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 |
A, B [auth C], C [auth E], D [auth G] | PF21010 | Helicase associated domain (HA2), ratchet-like (HA2_C) | Helicase associated domain (HA2), ratchet-like | The helicase associated domain (HA2) has an all alpha-helical fold and consists of a N-terminal winged-helix (WH) domain (Pfam:PF04408) and a C-terminal degenerate helical-bundle domain, referred to as the ratchet-like domain [1,2,3]. These domains c ... | Domain |
