Protein Domain
Type: Family
Description: This entry represents a group of helicases, including DNA2 and Nam7. Proteins in this family contain a conserved domain with s a P-loop motif that is characteristic of the AAA superfamily. They are DEAD-like helicases belonging to superfamily (SF)1, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. Similar to SF2 helicases, SF1 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 [, , ].Dna2 is a DNA replication factor with single-stranded DNA-dependent ATPase, ATP-dependent nuclease, (5'-flap endonuclease) and helicase activities [, ]. Nam7 (also known as Upf1) is an ATP-dependent RNA helicase involved in the nonsense-mediated mRNA decay (NMD) pathway [].
Protein Domain
Type: Family
Description: RNA helicases from the DEAD-box family are found in almost all organisms andhave important roles in RNA metabolism, such as splicing, RNA transport,ribosome biogenesis, translation and RNA decay. They are enzymes that unwinddouble-stranded RNA molecules in an energy dependent fashion through thehydrolysis of NTP. DEAD-box RNA helicases belong to superfamily 2 (SF2) ofhelicases. As other SF1 and SF2 members they contain seven conserved motifswhich are characteristic of these two superfamilies [].DEAD-box is named after the amino acids of motif II or Walker B (Mg2+-bindingaspartic acid). The RNA helicase DeaD is ATP-dependent []and is induced by low temperatures []. In addition to its role in unwinding double stranded RNA, it is involved in ribosomal subunit biogenesis [].

Protein Domain
Type: Domain
Description: This domain contains a P-loop motif that is characteristic of the AAA superfamily. Proteins containing this domain are DEAD-like helicases belonging to superfamily (SF)1, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. Similar to SF2 helicases, SF1 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 [, , ].Proteins containing this domain include helicases, such as Dna2 an Nam7. Dna2 is a DNA replication factor with single-stranded DNA-dependent ATPase, ATP-dependent nuclease, (5'-flap endonuclease) and helicase activities [, ]. Nam7 (also known as Upf1) is an ATP-dependent RNA helicase involved in the nonsense-mediated mRNA decay (NMD) pathway []. This domain can also be found in some virus polyproteins. This domain is also known as HelicC.
Protein Domain
Type: Domain
Description: This entry represents the RNA recognition motif (RRM) of SPF45. SPF45, also termed RNA-binding motif protein 17 (RBM17), is an RNA-binding protein consisting of an unstructured N-terminal region, followed by a G-patch motif and a C-terminal U2AF (U2 auxiliary factor) homology motifs (UHM) that harbours a RNA recognition motif (RRM) and an Arg-Xaa-Phe sequence motif. SPF45 is a bifunctional protein that functions in splicing and DNA repair. It is involved in regulating alternative splicing of the apoptosis regulatory gene FAS (also called CD95). Its UHM binds UHM-ligand motifs (ULMs) present in the 3' splice site-recognizing factors U2AF65, SF1 and SF3b155 []. It binds to the Holliday junction, which is a key DNA intermediate in the homologous-recombination pathway [, ].
Protein Domain
Type: Domain
Description: Nidoviruses (Coronaviridae, Arteriviridae, and Roniviridae) feature the most complex genetic organization among plus-strand RNA viruses. Their replicase genes encode an exceptionally large replicase polyprotein 1a/ab which is then proteolytically processed to release different nonstructural proteins (NSPs) that mediate the key functions required for replication and transcription. One of these NSPs, called NSP10 in arteriviruses (Av) and NSP13 in coronaviruses (CoV) functions as a helicase [, ]. It is a multidomain protein consisting of a N-terminal Cys/His rich zinc-binding domain (ZBD) and a helicase core that belongs to the superfamily SF1 of helicases. The helicase core contains two RecA1 and RecA2 domains and a 1B domain [].This entry represents the 1B domain, which has a regulatory role modulating the nucleic acid substrate binding. Based on the structures from the Equine arteritis virus (EAV) NSP10, 1B domain undergoes large conformational change upon substrate binding, and forms a channel together with 1A and 2A domains that accommodates the single stranded nucleic acids [, ].
Protein Domain
Type: Domain
Description: This helix-hairpin domain can be found in N-terminal region of mammalian splicing factor 1 (SF1) and fungal branchpoint binding proteins (BBP) []. These proteins are required for pre-spliceosome formation, which is the first step of pre-mRNA splicing [, ]. SF1 forms a complex with U2AF65 through the interaction between this domain and the C-terminal U2AF homology motif domain (UHM) of U2AF65. This domain forms a secondary, hydrophobic interface with U2AF65(UHM) to lock the orientation of the two subunits, which is essential for cooperative formation of the ternary SF1-U2AF65-RNA complex []. This domain contains a highly conserved SPSP motif at its C terminus; the phophorylation of the SPSP motif induces a disorder-to-order transition within a novel SF1/U2AF65 interface [].
Protein Domain
Type: Domain
Description: Helicases have been classified in 5 superfamilies (SF1-SF5). For the two largest groups, commonly referred to as SF1 and SF2, a total of seven characteristic motifs has been identified []. These two superfamilies encompass a large number of DNA and RNA helicases from archaea, eubacteria, eukaryotes and viruses.This entry represents the C-terminal domain found in proteins belonging to the helicase superfamilies 1 and 2. Included in this group is the eukaryotic translation initiation factor 4A (eIF4A), a member of the DEA(D/H)-box RNA helicase family. The structure of the carboxyl-terminal domain of eIF4A has been determined; it has a parallel α-β topology that superimposes, with minor variations, on the structures and conserved motifs of the equivalent domain in other, distantly related helicases [].

Description: Helicases have been classified in 5 superfamilies (SF1-SF5). All of the proteins bind ATP and, consequently, all of them carry the classical Walker A(phosphate-binding loop or P-loop) and Walker B(Mg2+-binding aspartic acid) motifs. For the two largest groups, commonlyreferred to as SF1 and SF2, a total of seven characteristic motifs has beenidentified []. These two superfamilies encompass a large number of DNA andRNA helicases from archaea, eubacteria, eukaryotes and viruses that seem to beactive as monomers or dimers. RNA and DNA helicases are considered to beenzymes that catalyze the separation of double-stranded nucleic acids in anenergy-dependent manner [].The various structures of SF1 and SF2 helicases present a common core with twoα-β RecA-like domains [, ]. Thestructural homology with the RecA recombination protein covers the fivecontiguous parallel beta strands and the tandem alpha helices. ATP binds tothe amino proximal α-β domain, where the Walker A (motif I) and WalkerB (motif II) are found. The N-terminal domain also contains motif III (S-A-T)which was proposed to participate in linking ATPase and helicase activities.The carboxy-terminal α-β domain is structurally very similar to theproximal one even though it is bereft of an ATP-binding site, suggesting thatit may have originally arisen through gene duplication of the first one.Some members of helicase superfamilies 1 and 2 are listed below:DEAD-box RNA helicases. The prototype of DEAD-boxproteins is the translation initiation factor eIF4A. The eIF4A protein isan RNA-dependent ATPase which functions together with eIF4B as an RNAhelicase [].DEAH-box RNA helicases.

Protein Domain
Type: Family
Description: Helicases have been classified in 5 superfamilies (SF1-SF5). All of the proteins bind ATP and, consequently, all of them carry the classical Walker A(phosphate-binding loop or P-loop) and Walker B(Mg2+-binding aspartic acid) motifs. For the two largest groups, commonlyreferred to as SF1 and SF2, a total of seven characteristic motifs has beenidentified []. These two superfamilies encompass a large number of DNA andRNA helicases from archaea, eubacteria, eukaryotes and viruses that seem to beactive as monomers or dimers. RNA and DNA helicases are considered to beenzymes that catalyze the separation of double-stranded nucleic acids in anenergy-dependent manner [].The various structures of SF1 and SF2 helicases present a common core with twoα-β RecA-like domains [, ]. Thestructural homology with the RecA recombination protein covers the fivecontiguous parallel beta strands and the tandem alpha helices. ATP binds tothe amino proximal α-β domain, where the Walker A (motif I) and WalkerB (motif II) are found. The N-terminal domain also contains motif III (S-A-T)which was proposed to participate in linking ATPase and helicase activities.The carboxy-terminal α-β domain is structurally very similar to theproximal one even though it is bereft of an ATP-binding site, suggesting thatit may have originally arisen through gene duplication of the first one.Some members of helicase superfamilies 1 and 2 are listed below:DEAD-box RNA helicases.
