>gnl|CDD|239644 cd03672, Dcp2p, mRNA decapping enzyme 2 (Dcp2p), the catalytic
           subunit, and Dcp1p are the two components of the
           decapping enzyme complex. Decapping is a key step in
           both general and nonsense-mediated 5'->3' mRNA-decay
           pathways. Dcp2p contains an all-alpha helical N-terminal
           domain and a C-terminal domain which has the Nudix fold.
           While decapping is not dependent on the N-terminus of
           Dcp2p, it does affect its efficiency. Dcp1p binds the
           N-terminal domain of Dcp2p stimulating the decapping
           activity of Dcp2p. Decapping permits the degradation of
           the transcript and is a site of numerous control inputs.
           It is responsible for nonsense-mediated decay as well as
           AU-rich element (ARE)-mediated decay. In addition, it
           may also play a role in the levels of mRNA. Enzymes
           belonging to the Nudix superfamily require a divalent
           cation, such as Mg2+ or Mn2+, for their activity and are
           recognized by a highly conserved 23-residue nudix motif
           (GX5EX7REUXEEXGU, where U = I, L or V).

>gnl|CDD|239217 cd02883, Nudix_Hydrolase, Nudix hydrolase is a superfamily of
           enzymes found in all three kingdoms of life, and it
           catalyzes the hydrolysis of NUcleoside DIphosphates
           linked to other moieties, X. Enzymes belonging to this
           superfamily require a divalent cation, such as Mg2+ or
           Mn2+ for their activity. Members of this family are
           recognized by a highly conserved 23-residue nudix motif
           (GX5EX7REUXEEXGU, where U = I, L or V), which forms a
           structural motif that functions as a metal binding and
           catalytic site. Substrates of nudix hydrolase include
           intact and oxidatively damaged nucleoside triphosphates,
           dinucleoside polyphosphates, nucleotide-sugars and
           dinucleotide enzymes. These substrates are metabolites
           or cell signaling molecules that require regulation
           during different stages of the cell cycle or during
           periods of stress. In general, the role of the nudix
           hydrolase is to sanitize the nucleotide pools and to
           maintain cell viability, thereby serving as surveillance
           and "house-cleaning" enzymes. Substrate specificity is
           used to define child families within the superfamily.
           Differences in substrate specificity are determined by
           the N-terminal extension or by residues in variable loop
           regions. Mechanistically, substrate hydrolysis occurs by
           a nucleophilic substitution reaction, with variation in
           the numbers and roles of divalent cations required. This
           superfamily consists of at least nine families: IPP
           (isopentenyl diphosphate) isomerase, ADP ribose
           pyrophosphatase, mutT pyrophosphohydrolase, coenzyme-A
           pyrophosphatase,
           MTH1-7,8-dihydro-8-oxoguanine-triphosphatase,
           diadenosine tetraphosphate hydrolase, NADH
           pyrophosphatase, GDP-mannose hydrolase and the
           c-terminal portion of the mutY adenine glycosylase.

>gnl|CDD|239520 cd03428, Ap4A_hydrolase_human_like, Diadenosine tetraphosphate
           (Ap4A) hydrolase is a member of the Nudix hydrolase
           superfamily. Ap4A hydrolases are well represented in a
           variety of prokaryotic and eukaryotic organisms.
           Phylogenetic analysis reveals two distinct subgroups
           where plant enzymes fall into one subfamily and
           fungi/animals/archaea enzymes, represented by this
           subfamily, fall into another. Bacterial enzymes are
           found in both subfamilies. Ap4A is a potential
           by-product of aminoacyl tRNA synthesis, and accumulation
           of Ap4A has been implicated in a range of biological
           events, such as DNA replication, cellular
           differentiation, heat shock, metabolic stress, and
           apoptosis. Ap4A hydrolase cleaves Ap4A asymmetrically
           into ATP and AMP. It is important in the invasive
           properties of bacteria and thus presents a potential
           target for inhibition of such invasive bacteria. Besides
           the signature nudix motif (G[X5]E[X7]REUXEEXGU, where U
           is Ile, Leu, or Val) that functions as a metal binding
           and catalytic site, and a required divalent cation, Ap4A
           hydrolase is structurally similar to the other members
           of the nudix superfamily with some degree of variation.
           Several regions in the sequences are poorly defined and
           substrate and metal binding sites are only predicted
           based on kinetic studies.

>gnl|CDD|239645 cd03673, Ap6A_hydrolase, Diadenosine hexaphosphate (Ap6A) hydrolase
           is a member of the Nudix hydrolase superfamily. Ap6A
           hydrolase specifically hydrolyzes diadenosine
           polyphosphates, but not ATP or diadenosine triphosphate,
           and it generates ATP as the product. Ap6A, the most
           preferred substrate, hydrolyzes to produce two ATP
           molecules, which is a novel hydrolysis mode for Ap6A.
           These results indicate that Ap6A  hydrolase is a
           diadenosine polyphosphate hydrolase. It requires the
           presence of a divalent cation, such as Mn2+, Mg2+, Zn2+,
           and Co2+, for activity. Members of the Nudix superfamily
           are recognized by a highly conserved 23-residue nudix

           catalyzes the hydrolysis of ADP-ribose and a variety of
           additional ADP-sugar conjugates to AMP and
           ribose-5-phosphate. Like other members of the Nudix

           such as Mg2+, for its activity. It also contains a
           highly conserved 23-residue Nudix motif
           (GX5EX7REUXEEXGU, where U = I, L or V) which functions
           as a metal binding site/catalytic site. In addition to
           the Nudix motif, there are additional conserved amino
           acid residues, distal from the signature sequence, that
           correlate with substrate specificity. In humans, there
           are four distinct ADPRase activities, three putative
           cytosolic enzymes (ADPRase-I, -II, and -Mn) and a single
           mitochondrial enzyme (ADPRase-m). Human ADPRase-II is
           also referred to as NUDT5. It lacks the N-terminal
           target sequence unique to mitochondrial ADPRase. The
           different cytosolic types are distinguished by their
           specificities for substrate and specific requirement for
           metal ions. NUDT5 forms a homodimer.

>gnl|CDD|239519 cd03427, MTH1, MutT homolog-1 (MTH1) is a member of the Nudix
           hydrolase superfamily. MTH1, the mammalian counterpart
           of MutT, hydrolyzes oxidized purine nucleoside
           triphosphates, such as 8-oxo-dGTP and 2-hydroxy-ATP, to
           monophosphates, thereby preventing the incorporation of
           such oxygen radicals during replication. This is an
           important step in the repair mechanism in genomic and
           mitochondrial DNA.  Like other members of the Nudix
           family, it requires a divalent cation, such as Mg2+ or
           Mn2+, for activity, and contain the Nudix motif, a
           highly conserved 23-residue block (GX5EX7REUXEEXGU,
           where U = I, L or V), that functions as a metal binding
           and catalytic site. MTH1 is predominantly localized in
           the cytoplasm and mitochondria. Structurally, this
           enzyme adopts a similar fold to MutT despite low
           sequence similarity outside the conserved nudix motif.
           The most distinctive structural difference between MutT
           and MTH1 is the presence of a beta-hairpin, which is
           absent in MutT. This results in a much deeper and
           narrower substrate binding pocket. Mechanistically, MTH1
           contains dual specificity for nucleotides that contain
           2-OH-adenine bases and those that contain 8-oxo-guanine
           bases.

           triphosphates (NTPs and dNTPs) by substitution at a
           beta-phosphorus to yield a nucleotide monophosphate
           (NMP) and inorganic pyrophosphate (PPi). This enzyme
           requires two divalent cations for activity; one
           coordinates the phosphoryl groups of the NTP/dNTP
           substrate, and the other coordinates to the enzyme. It
           also contains the Nudix motif, a highly conserved
           23-residue block (GX5EX7REUXEEXGU, where U = I, L or V),
           that functions as metal binding and catalytic site. MutT
           pyrophosphohydrolase is important in preventing errors
           in DNA replication by hydrolyzing mutagenic nucleotides
           such as 8-oxo-dGTP (a product of oxidative damage),
           which can mispair with template adenine during DNA

           triphosphatase and dinucleoside polyphosphate
           pyrophosphatase activities. Like other enzymes belonging
           to this superfamily, it requires a divalent cation, in
           this case Mg2+, for its activity. It also contains a
           highly conserved 23-residue nudix motif
           (GX5EX7REUXEEXGU, where U = I, L or V), which functions
           as a metal binding and catalytic site. In general,
           substrates of nudix hydrolases include intact and
           oxidatively damaged nucleoside triphosphates,
           dinucleoside polyphosphates, nucleotide-sugars and
           dinucleotide enzymes. These substrates are metabolites
           or cell signaling molecules that require regulation
           during different stages of the cell cycle or during
           periods of stress. In general, the role of the nudix
           hydrolase is to sanitize the nucleotide pools and to
           maintain cell viability, thereby serving as surveillance
           & "house-cleaning" enzymes. Substrate specificity is
           used to define families within the superfamily.
           Differences in substrate specificity are determined by
           the N-terminal extension or by residues in variable loop
           regions. Mechanistically, substrate hydrolysis occurs by
           a nucleophilic substitution reaction, with variation in
           the numbers and roles of divalent cations required.

           N-acetylated proteins. N-terminal acetylation of
           proteins is a widespread and highly conserved process
           that is involved in protection and stability of
           proteins. Several types of aminoacylases can be
           distinguished on the basis of substrate specificity.
           Aminoacylase 1 (ACY1) breaks down cytosolic aliphatic
           N-acyl-alpha-amino acids (except L-aspartate),
           especially N-acetyl-methionine and acetyl-glutamate into
           L-amino acids and an acyl group. However, ACY1 can also
           catalyze the reverse reaction, the synthesis of
           acetylated amino acids. ACY1 may also play a role in
           xenobiotic bioactivation as well as the inter-organ
           processing of amino acid-conjugated xenobiotic
           derivatives (S-substituted-N-acetyl-L-cysteine).

>gnl|CDD|153177 cd04905, ACT_CM-PDT, C-terminal ACT domain of the bifunctional
          chorismate mutase-prephenate dehydratase (CM-PDT)
          enzyme and the prephenate dehydratase (PDT) enzyme.
          The C-terminal ACT domain of the bifunctional
          chorismate mutase-prephenate dehydratase (CM-PDT)
          enzyme and the prephenate dehydratase (PDT) enzyme,
          found in plants, fungi, bacteria, and archaea. The
          P-protein of E. coli (CM-PDT, PheA) catalyzes the
          conversion of chorismate to prephenate and then the
          decarboxylation and dehydration to form phenylpyruvate.
          These are the first two steps in the biosynthesis of
          L-Phe and L-Tyr via the shikimate pathway in
          microorganisms and plants. The E. coli P-protein
          (CM-PDT) has three domains with an N-terminal domain
          with chorismate mutase activity, a middle domain with
          prephenate dehydratase activity, and an ACT regulatory
          C-terminal domain. The prephenate dehydratase enzyme
          has a PDT and ACT domain. The ACT domain is essential
          to bring about the negative allosteric regulation by
          L-Phe binding. L-Phe binds with positive cooperativity;
          with this binding, there is a shift in the protein to
          less active tetrameric and higher oligomeric forms from
          a more active dimeric form. Members of this CD belong
          to the superfamily of ACT regulatory domains.

>gnl|CDD|240040 cd04684, Nudix_Hydrolase_25, Contains a crystal structure of the
           Nudix hydrolase from Enterococcus faecalis, which has an
           unknown function. In general, members of the Nudix
           hydrolase superfamily catalyze the hydrolysis of
           NUcleoside DIphosphates linked to other moieties, X.
           Enzymes belonging to this superfamily require a divalent
           cation, such as Mg2+ or Mn2+, for their activity. They
           also contain a highly conserved 23-residue nudix motif
           (GX5EX7REUXEEXGU, where U = I, L or V), which forms a
           structural motif that functions as a metal binding and
           catalytic site. Substrates of nudix hydrolases include
           intact and oxidatively damaged nucleoside triphosphates,
           dinucleoside polyphosphates, nucleotide-sugars and
           dinucleotide enzymes. These substrates are metabolites
           or cell signaling molecules that require regulation
           during different stages of the cell cycle or during
           periods of stress. In general, the role of the nudix
           hydrolase is to sanitize the nucleotide pools and to
           maintain cell viability, thereby serving as surveillance
           & "house-cleaning" enzymes. Substrate specificity is
           used to define families within the superfamily.
           Differences in substrate specificity are determined by
           the N-terminal extension or by residues in variable loop
           regions. Mechanistically, substrate hydrolysis occurs by
           a nucleophilic substitution reaction, with variation in
           the numbers and roles of divalent cations required.
