RNA helicase HrpA; This model represents HrpA, one of two related but uncharacterized DEAH-box ATP-dependent helicases in many Proteobacteria and a few high-GC Gram-positive bacteria. HrpA is about 1300 amino acids long, while its paralog HrpB, also uncharacterized, is about 800 amino acids long. Related characterized eukarotic proteins are RNA helicases associated with pre-mRNA processing. The HrpA/B homolog from Borrelia is 500 amino acids shorter but appears to be derived from HrpA rather than HrpB. [Unknown function, Enzymes of unknown specificity]

C-terminal helicase domain of the RNA helicase A (RHA) family helicases; The RNA helicase A (RHA) family includes RHA, also called DEAH-box helicase 9 (DHX9), DHX8, DHX15-16, DHX32-38, and many others. The RHA family members are DEAD-like helicases belonging to superfamily (SF)2, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. Similar to SF1 helicases, SF2 helicases do not form toroidal structures like SF3-6 helicases. Their helicase core consists of two similar protein domains that resemble the fold of the recombination protein RecA. This model describes the C-terminal domain, also called HelicC.

Oligonucleotide/oligosaccharide-binding (OB)-fold; This family is found towards the C-terminus of the DEAD-box helicases (pfam00270). In these helicases it is apparently always found in association with pfam04408. There do seem to be a couple of instances where it occurs by itself -. The structure PDB:3i4u adopts an OB-fold. helicases (pfam00270). In these helicases it is apparently always found in association with pfam04408. This C-terminal domain of the yeast helicase contains an oligonucleotide/oligosaccharide-binding (OB)-fold which seems to be placed at the entrance of the putative nucleic acid cavity. It also constitutes the binding site for the G-patch-containing domain of Pfa1p. When found on DEAH/RHA helicases, this domain is central to the regulation of the helicase activity through its binding of both RNA and G-patch domain proteins.

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.

C-terminal helicase domain of superfamily 2 DEAD/H-box helicases; Superfamily (SF)2 helicases include DEAD-box helicases, UvrB, RecG, Ski2, Sucrose Non-Fermenting (SNF) family helicases, and dicer proteins, among others. Similar to SF1 helicases, they do not form toroidal structures like SF3-6 helicases. SF2 helicases are a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. Their helicase core is surrounded by C- and N-terminal domains with specific functions such as nucleases, RNA or DNA binding domains, or domains engaged in protein-protein interactions. The core consists of two similar protein domains that resemble the fold of the recombination protein RecA. This model describes the C-terminal domain, also called HelicC.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.

Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.

(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
