DEXXQ-box helicase domain of DNA2; DNA2 (DNA Replication Helicase/Nuclease 2) possesses different enzymatic activities, such as single-stranded DNA (ssDNA)-dependent ATPase, 5-3 helicase, and endonuclease activities, and is involved in DNA replication and DNA repair in the nucleus and mitochondrion. It is involved in Okazaki fragment processing by cleaving long flaps that escape FEN1: flaps that are longer than 27 nucleotides are coated by replication protein A complex (RPA), leading to recruit DNA2 which cleaves the flap until it is too short to bind RPA and becomes a substrate for FEN1. It is also involved in 5-end resection of DNA during double-strand break (DSB) repair; it is recruited by BLM and mediates the cleavage of 5-ssDNA, while the 3-ssDNA cleavage is prevented by the presence of RPA. DNA2 is a member of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

DEXXQ-box helicase domain of SETX; The RNA/DNA helicase senataxin (SETX) plays a role in transcription, neurogenesis, and antiviral response. SEXT is an R-loop-associated protein that is thought to function as an RNA/DNA helicase. R-loops consist of RNA/DNA hybrids, formed during transcription when nascent RNA hybridizes to the DNA template strand, displacing the non-template DNA strand. Mutations in SETX are linked to two neurodegenerative disorders: ataxia with oculomotor apraxia type 2 (AOA2) and amyotrophic lateral sclerosis type 4 (ALS4). S. cerevisiae homolog splicing endonuclease 1 (Sen1) is an exclusively nuclear protein, important for nucleolar organization. S. cerevisiae Sen1 and its ortholog, the Schizosaccharomyces pombe Sen1, share conserved domains and belong to the family I class of helicases. Both proteins translocate 5' to 3' and unwind both DNA and RNA duplexes and also RNA/DNA hybrids in vitro. SETX is a member of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

DEXXQ-box helicase domain of UPF1; UPF1 (also called RNA Helicase And ATPase, Regulator Of Nonsense Transcripts, or ATP-Dependent Helicase RENT1) is an RNA-dependent helicase and ATPase required for nonsense-mediated decay (NMD) of mRNAs containing premature stop codons. It is recruited to mRNAs upon translation termination and undergoes a cycle of phosphorylation and dephosphorylation; its phosphorylation appears to be a key step in NMD. It is recruited by release factors to stalled ribosomes together with the SMG1C protein kinase complex to form the transient SURF (SMG1-UPF1-eRF1-eRF3) complex. In EJC-dependent NMD, the SURF complex associates with the exon junction complex (EJC) located downstream from the termination codon through UPF2 and allows the formation of an UPF1-UPF2-UPF3 surveillance complex which is believed to activate NMD. Diseases associated with UPF1 include juvenile amyotrophic lateral sclerosis and epidermolysis bullosa, junctional, non-Herlitz type. UPF1 is a member of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

NFX1 binds a conserved cis-acting element, termed the X-box, in promoters of human class II MHC genes. The Cys-rich region contains several NFX1-type zinc finger domains. Frequently, a R3H domain is present in the C-terminus, and a RING finger domain and a PAM2 motif are present in the N-terminus. The lack of R3H and PAM2 motifs in the plant proteins indicates functional differences. Plant NFX1-like proteins are proposed to modulate growth and survival by coordinating reactive oxygen species, salicylic acid, further biotic stress and abscisic acid responses. A common feature of all members may be E3 ubiquitin ligase, due to the presence of a RING finger domain, as well as DNA binding.

N-terminal DEXXQ-box helicase domain of HELZ2; Helicase with zinc finger 2 (HELZ2, also known as PPAR-alpha-interacting complex protein 285 or PRIC285 and PPAR-gamma DBD-interacting protein 1 or PDIP1) acts as a transcriptional coactivator for a number of nuclear receptors including PPARA, PPARG, THRA, THRB, and RXRA. It belongs to the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

DEXH-box helicase domain of type III restriction enzyme res subunit; Members of this model includes both type I and type III restriction enzymes. Both are hetero-oligomeric proteins. Type I REs are encoded by three closely linked genes: a specificity subunit (HsdS or S) for recognizing a DNA sequence, a methylation subunit (HsdM or M) for methylating the recognized target bases, and a restriction subunit (HsdR or R) for the translocation and random cleavage of non-methylated DNA. They show diverse catalytic activities, including methyltransferase (MTase), ATP hydrolase (ATPase), DNA translocation and restriction activities. These enzymes cut at a site that differs, and is a random distance (at least 1000 bp) away, from their recognition site. Cleavage at these random sites follows a process of DNA translocation, which shows that these enzymes are also molecular motors. The recognition site is asymmetrical and is composed of two specific portions: one containing 3-4 nucleotides, and another containing 4-5 nucleotides, separated by a non-specific spacer of about 6-8 nucleotides. Type III enzymes are composed of two subunits, Res and Mod. The Mod subunit recognizes the DNA sequence specific for the system and is a modification methyltransferase; as such, it is functionally equivalent to the M and S subunits of type I restriction endonucleases. Res is required for restriction, although it has no enzymatic activity on its own. Type III enzymes recognize short 5-6 bp-long asymmetric DNA sequences and cleave 25-27 bp downstream to leave short, single-stranded 5' protrusions. They require the presence of two inversely oriented unmethylated recognition sites for restriction to occur. These enzymes methylate only one strand of the DNA, at the N-6 position of adenosyl residues, so newly replicated DNA will have only one strand methylated, which is sufficient to protect against restriction. Both type I and type III REs are members of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

helicase domain of betacoronavirus non-structural protein 13; This model represents the helicase domain of non-structural protein 13 (Nsp13) from betacoronavirus, including pathogenic human viruses such as Severe acute respiratory syndrome coronavirus (SARS-CoV), SARS-CoV2 (also called 2019 novel CoV or 2019-nCoV), and Middle East respiratory syndrome-related (MERS) CoV. Helicases catalyze NTP-dependent unwinding of nucleic acid duplexes into single strands and are classified based on the arrangement of conserved motifs into six superfamilies. CoV Nsp13 is a member of the helicase superfamily 1 (SF1); SF1 and SF2 helicases do not form toroidal structures, while SF3-6 helicases do. Nsp13 is a component of the viral RNA synthesis replication and transcription complex (RTC). It is a multidomain protein containing a Cys/His rich zinc-binding domain (CH/ZBD), a stalk domain, a 1B domain involved in nucleic acid substrate binding, and a SF1 helicase core.

The AAA+ (ATPases Associated with a wide variety of cellular Activities) superfamily represents an ancient group of ATPases belonging to the ASCE (for additional strand, catalytic E) division of the P-loop NTPase fold. The ASCE division also includes ABC, RecA-like, VirD4-like, PilT-like, and SF1/2 helicases. Members of the AAA+ ATPases function as molecular chaperons, ATPase subunits of proteases, helicases, or nucleic-acid stimulated ATPases. The AAA+ proteins contain several distinct features in addition to the conserved alpha-beta-alpha core domain structure and the Walker A and B motifs of the P-loop NTPases.
