 11-166 2.98e-59

DEDDh 3'-5' exonuclease domain family; DEDDh exonucleases, part of the DnaQ-like (or DEDD) exonuclease superfamily, catalyze the excision of nucleoside monophosphates at the DNA or RNA termini in the 3'-5' direction. These proteins contain four invariant acidic residues in three conserved sequence motifs termed ExoI, ExoII and ExoIII. DEDDh exonucleases are classified as such because of the presence of specific Hx(4)D conserved pattern at the ExoIII motif. The four conserved acidic residues are clustered around the active site and serve as ligands for the two metal ions required for catalysis. Most DEDDh exonucleases are the proofreading subunits (epsilon) or domains of bacterial DNA polymerase III, the main replicating enzyme in bacteria, which functions as the chromosomal replicase. Other members include other DNA and RNA exonucleases such as RNase T, Oligoribonuclease, and RNA exonuclease (REX), among others.

 10-162 5.45e-31

DnaQ family exonuclease/DinG family helicase, putative; This model represents a family of proteins in Gram-positive bacteria. The N-terminal region of about 200 amino acids resembles the epsilon subunit of E. coli DNA polymerase III and the homologous region of the Gram-positive type DNA polymerase III alpha subunit. The epsilon subunit contains an exonuclease domain. The remainder of this protein family resembles a predicted ATP-dependent helicase, the DNA damage-inducible protein DinG of E. coli.

DEDDh 3'-5' exonuclease domain family; DEDDh exonucleases, part of the DnaQ-like (or DEDD) exonuclease superfamily, catalyze the excision of nucleoside monophosphates at the DNA or RNA termini in the 3'-5' direction. These proteins contain four invariant acidic residues in three conserved sequence motifs termed ExoI, ExoII and ExoIII. DEDDh exonucleases are classified as such because of the presence of specific Hx(4)D conserved pattern at the ExoIII motif. The four conserved acidic residues are clustered around the active site and serve as ligands for the two metal ions required for catalysis. Most DEDDh exonucleases are the proofreading subunits (epsilon) or domains of bacterial DNA polymerase III, the main replicating enzyme in bacteria, which functions as the chromosomal replicase. Other members include other DNA and RNA exonucleases such as RNase T, Oligoribonuclease, and RNA exonuclease (REX), among others.

 10-165 3.99e-40

an uncharacterized bacterial subgroup of the DEDDh 3'-5' exonuclease domain family with similarity to the epsilon subunit of DNA polymerase III; This subfamily is composed of uncharacterized bacterial proteins with similarity to the epsilon subunit of DNA polymerase III (Pol III), a multisubunit polymerase which is the main DNA replicating enzyme in bacteria, functioning as the chromosomal replicase. The Pol III holoenzyme is a complex of ten different subunits, three of which (alpha, epsilon, and theta) compose the catalytic core. The Pol III epsilon subunit, encoded by the dnaQ gene, is a DEDDh-type 3'-5' exonuclease which is responsible for the proofreading activity of the polymerase, increasing the fidelity of DNA synthesis. It contains three conserved sequence motifs termed ExoI, ExoII and ExoIII, with a specific Hx(4)D conserved pattern at ExoIII. These motifs are clustered around the active site and contain four conserved acidic residues that serve as ligands for the two metal ions required for catalysis. The epsilon subunit of Pol III also functions as a stabilizer of the holoenzyme complex.

DnaQ family exonuclease/DinG family helicase, putative; This model represents a family of proteins in Gram-positive bacteria. The N-terminal region of about 200 amino acids resembles the epsilon subunit of E. coli DNA polymerase III and the homologous region of the Gram-positive type DNA polymerase III alpha subunit. The epsilon subunit contains an exonuclease domain. The remainder of this protein family resembles a predicted ATP-dependent helicase, the DNA damage-inducible protein DinG of E. coli.

exonuclease, DNA polymerase III, epsilon subunit family; All proteins in this family for which functions are known are components of the DNA polymerase III complex (epsilon subunit). There is, however, an outgroup that includes paralogs in some gamma-proteobacteria and the n-terminal region of DinG from some low GC gram positive bacteria. This family is based on the phylogenomic analysis of JA Eisen (1999, Ph.D. Thesis, Stanford University). [DNA metabolism, Degradation of DNA]

 10-168 3.88e-22

DEDDh 3'-5' exonuclease domain of Caenorhabditis elegans ERI-1, human 3' exonuclease, and similar proteins; This subfamily is composed of Caenorhabditis elegans ERI-1, human 3' exonuclease (3'hExo), Drosophila exonuclease snipper (snp), and similar proteins from eukaryotes and bacteria. These are DEDDh-type DnaQ-like 3'-5' exonucleases containing three conserved sequence motifs termed ExoI, ExoII and ExoIII, with a specific Hx(4)D conserved pattern at ExoIII. These motifs are clustered around the active site and contain four conserved acidic residues that serve as ligands for the two metal ions required for catalysis. ERI-1 has been implicated in the degradation of small interfering RNAs (RNAi). 3'hExo participates in the degradation of histone mRNAs. Snp is a non-essential exonuclease that efficiently degrades structured RNA and DNA substrates as long as there is a minimum of 2 nucleotides in the 3' overhang to initiate degradation. Snp is not a functional homolog of either ERI-1 or 3'hExo.

 11-166 7.58e-08

DEDDh 3'-5' exonuclease domain of the eukaryotic exoribonucleases PAN2, RNA exonuclease (REX)-1,-3, and -4, ISG20, and similar proteins; This group is composed of eukaryotic exoribonucleases that include PAN2, RNA exonuclease 1 (REX1 or Rex1p), REX3 (Rex3p), REX4 (or Rex4p), ISG20, and similar proteins. They are DEDDh-type DnaQ-like 3'-5' exonucleases containing three conserved sequence motifs termed ExoI, ExoII and ExoIII, with a specific Hx(4)D conserved pattern at ExoIII. These motifs are clustered around the active site and contain four conserved acidic residues that serve as ligands for the two metal ions required for catalysis. PAN2 is the catalytic subunit of poly(A) nuclease (PAN), a Pab1p-dependent 3'-5' exoribonuclease which plays an important role in the posttranscriptional maturation of pre-mRNAs. REX proteins are required for the processing and maturation of many RNA species, and ISG20 is an interferon-induced antiviral exonuclease with a strong preference for single-stranded RNA.

 9-162 1.66e-07

3'-5' exoribonuclease Rv2179c-like domain; This is a highly divergent 3' exoribonuclease family. The proteins constitute a typical RNase fold, where the active site residues form a magnesium catalytic centre. The protein of the solved structure readily cleaves 3' overhangs in a time-dependent manner. It is similar to DEDD-type RNases and is an unusual ATP-binding protein that binds ATP and dATP. It forms a dimer in solution and both protomers in the asymmetric unit bind a magnesium ion through Asp-6 in SwissProt:P9WJ73. Proteins containing this domain also include 3'-5' exonuclease dexA from bacteriophage T4. It may play a role in the final step of host DNA degradation, by scavenging DNA into mononucleotides.

 11-126 7.09e-07

DEDDh 3'-5' exonuclease domain of RNase T; RNase T is a DEDDh-type DnaQ-like 3'-5' exoribonuclease E implicated in the 3' maturation of small stable RNAs and 23srRNA, and in the end turnover of tRNA. It contains three conserved sequence motifs termed ExoI, ExoII and ExoIII, with a specific Hx(4)D conserved pattern at ExoIII. These motifs are clustered around the active site and contain four conserved acidic residues that serve as ligands for the two metal ions required for catalysis. RNase T is related to the proofreading domain of DNA polymerase III. Despite its important role, RNase T is mainly found only in gammaproteobacteria. It is speculated that it might have originated from DNA polymerase III at the time the gamma division of proteobacteria diverged from other bacteria. RNase T is a homodimer with the catalytic residues of one monomer contacting a large basic patch on the other monomer to form a functional active site.

DEDDh 3'-5' exonuclease domain of three prime repair exonuclease (TREX)1, TREX2, and similar ...
 10-165 1.17e-06

DEDDh 3'-5' exonuclease domain of three prime repair exonuclease (TREX)1, TREX2, and similar proteins; Three prime repair exonuclease (TREX)1 and TREX2 are closely related DEDDh-type DnaQ-like 3'-5' exonucleases. They contain three conserved sequence motifs known as ExoI, II, and III, with a specific Hx(4)D conserved pattern at ExoIII. These motifs contain four conserved acidic residues that participate in coordination of divalent metal ions required for catalysis. Both proteins play a role in the metabolism and clearance of DNA. TREX1 is the major 3'-5' exonuclease activity detected in mammalian cells. Mutations in the human TREX1 gene can cause Aicardi-Goutieres syndrome (AGS), which is characterized by perturbed innate immunity and presents itself as a severe neurological disease. TREX1 degrades ssDNA generated by aberrant replication intermediates to prevent checkpoint activation and autoimmune disease. There are distinct structural differences between TREX1 and TREX2 that point to different biological roles for these proteins. The main difference is the presence of about 70 amino acids at the C-terminus of TREX1. In addition, TREX1 has a nonrepetitive proline-rich region that is not present in the TREX2 protein. Furthermore, TREX2 contains a conserved DNA binding loop positioned adjacent to the active site that has a sequence distinct from the corresponding loop in TREX1. Truncations in the C-terminus of human TREX1 cause autosomal dominant retinal vasculopathy with cerebral leukodystrophy (RVCL), a neurovascular syndrome featuring a progressive loss of visual acuity combined with a variable neurological picture.

 29-166 1.98e-05

DEDDh 3'-5' exonuclease domain of RNA exonuclease 4, XPMC2, Interferon Stimulated Gene product of 20 kDa, and similar proteins; This subfamily is composed of RNA exonuclease 4 (REX4 or Rex4p), XPMC2, Interferon (IFN) Stimulated Gene product of 20 kDa (ISG20), and similar proteins. REX4 is involved in pre-rRNA processing. It controls the ratio between the two forms of 5.8S rRNA in yeast. XPMC2 is a Xenopus gene which was identified through its ability to correct a mitotic defect in fission yeast. The human homolog of XPMC2 (hPMC2) may be involved in angiotensin II-induced adrenal cell cycle progression and cell proliferation. ISG20 is an IFN-induced antiviral exonuclease with a strong preference for single-stranded RNA and minor activity towards single-stranded DNA. These proteins are DEDDh-type DnaQ-like 3'-5' exonucleases containing three conserved sequence motifs termed ExoI, ExoII and ExoIII, with a specific Hx(4)D conserved pattern at ExoIII. These motifs are clustered around the active site and contain four conserved acidic residues that serve as ligands for the two metal ions required for catalysis. REX proteins function in the processing and maturation of many RNA species, similar to the function of Escherchia coli RNase T.

DEDDh 3'-5' exonuclease domain of RNA exonuclease 1, -3 and similar eukaryotic proteins; This subfamily is composed of RNA exonuclease 1 (REX1 or Rex1p), REX3 (or Rex3p), and similar eukaryotic proteins. In yeast, REX1 and REX3 are required for 5S rRNA and MRP (mitochondrial RNA processing) RNA maturation, respectively. They are DEDDh-type DnaQ-like 3'-5' exonucleases containing three conserved sequence motifs termed ExoI, ExoII and ExoIII, with a specific Hx(4)D conserved pattern at ExoIII. These motifs are clustered around the active site and contain four conserved acidic residues that serve as ligands for the two metal ions required for catalysis. REX1 is the major exonuclease responsible for pre-tRNA trail trimming and may also be involved in nuclear CCA turnover. REX proteins function in the processing and maturation of many RNA species, similar to the function of Escherichia coli RNase T.
