>gnl|CDD|239642 cd03670, ADPRase_NUDT9, ADP-ribose pyrophosphatase (ADPRase)
catalyzes the hydrolysis of ADP-ribose to AMP and
ribose-5-P. Like other members of the Nudix hydrolase
superfamily of enzymes, it is thought to require a
divalent cation, such as Mg2+, for its activity. It also
contains a 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
(ADPRase-I, -II, and -Mn) and a single mitochondrial
enzyme (ADPRase-m). ADPRase-m is also known as NUDT9. It
can be distinugished from the cytosolic ADPRase by a
N-terminal target sequence unique to mitochondrial
ADPRase. NUDT9 functions as a monomer.

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 and contain a
highly conserved 23-residue nudix motif
(GX5EX7REUXEEXGU, where U = I, L or V), which 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.

>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|217343 pfam03059, NAS, Nicotianamine synthase protein. Nicotianamine
synthase EC:2.5.1.43 catalyzes the trimerisation of
S-adenosylmethionine to yield one molecule of
nicotianamine. Nicotianamine has an important role in
plant iron uptake mechanisms. Plants adopt two
strategies (termed I and II) of iron acquisition.
Strategy I is adopted by all higher plants except
graminaceous plants, which adopt strategy II. In
strategy I plants, the role of nicotianamine is not
fully determined: possible roles include the formation
of more stable complexes with ferrous than with ferric
ion, which might serve as a sensor of the physiological
status of iron within a plant, or which might be
involved in the transport of iron. In strategy II
(graminaceous) plants, nicotianamine is the key
intermediate (and nicotianamine synthase the key enzyme)
in the synthesis of the mugineic family (the only known
family in plants) of phytosiderophores.
Phytosiderophores are iron chelators whose secretion by
the roots is greatly increased in instances of iron
deficiency. The 3D structures of five example NAS from
Methanothermobacter thermautotrophicus reveal the
monomer to consist of a five-helical bundle N-terminal
domain on top of a classic Rossmann fold C-terminal
domain. The N-terminal domain is unique to the NAS
family, whereas the C-terminal domain is homologous to
the class I family of SAM-dependent methyltransferases.
An active site is created at the interface of the two
domains, at the rim of a large cavity that corresponds
to the nucleotide binding site such as is found in other
proteins adopting a Rossmann fold.

oxalacetate by reductive carboxylation of pyruvate.

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
hydrolase superfamily, it requires a divalent cation,
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.
