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.

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

variety of prokaryotic and eukaryotic organisms.
Phylogenetic analysis reveals two distinct subgroups

fungi/animals/archaea enzymes, represented by this

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

based on kinetic studies.

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

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.

>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

the elimination of oxidized inactive CoA, which can

CoA plays a central role in lipid metabolism. It is
involved in the initial steps of fatty acid sythesis in
the cytosol, in the oxidation of fatty acids and the
citric acid cycle in the mitochondria, and in the
oxidation of long-chain fatty acids in peroxisomes. CoA

O-acetyltransferase NeuD family. This family of
proteins includes the characterized NeuD sialic acid
O-acetyltransferase enzymes from E. coli and
Streptococcus agalactiae (group B strep). These two are
quite closely related to one another, so extension of
this annotation to other members of the family in
unsupported without additional independent evidence. The
neuD gene is often observed in close proximity to the
neuABC genes for the biosynthesis of
CMP-N-acetylneuraminic acid (CMP-sialic acid), and NeuD
sequences from these organisms were used to construct
the seed for this model. Nevertheless, there are
numerous instances of sequences identified by this model
which are observed in a different genomic context
(although almost universally in exopolysaccharide
biosynthesis-related loci), as well as in genomes for
which the biosynthesis of sialic acid (SA) is
undemonstrated. Even in the cases where the association
with SA biosynthesis is strong, it is unclear in the
literature whether the biological substrate is SA
iteself, CMP-SA, or a polymer containing SA. Similarly,
it is unclear to what extent the enzyme has a preference
for acetylation at the 7, 8 or 9 positions. In the
absence of evidence of association with SA, members of
this family may be involved with the acetylation of
differring sugar substrates, or possibly the delivery of
alternative acyl groups. The closest related sequences
to this family (and those used to root the phylogenetic
tree constructed to create this model) are believed to
be succinyltransferases involved in lysine biosynthesis.
These proteins contain repeats of the bacterial
transferase hexapeptide (pfam00132), although often
these do not register above the trusted cutoff.

family of bacterial protein modules thought to function
in various roles including cell adhesion, cell lysis and
carbohydrate binding. The beta-sandwich jelly-roll
topology of these modules is known as the
galactose-binding domain-like superfamily, clan CL0202.
A tandem repeat of these modules (either two or three
repeats) constitute the haemagglutinin/adhesin (HA)
regions of the gingipains, RgpA, and Kgp, and
Lys-gingipain HG66 expressed by Porphyromonas gingivalis
(Bacteroides gingivalis). They form components of the
major extracellular virulence complex RgpA-Kgp - a
mixture of proteinases and adhesin domains. The adhesin
domains in this complex are found in proteinase-cleaved
forms when isolated from the cell surface.
Haemagglutinin genes of P. gingivalis (hagA1 HAGA1_PORGI
- and hagA2 HAGA2_PORGI) suggest that such proteins are
composed of eight to ten tandem repeats of these adhesin
modules. Genomic data predicts that homologous protein
modules are also expressed by a number of other bacteria
and form part of putative multi-domain proteins. These
domains may be acting in concert with other adhesion
modules thought to be part of these multi-domain
proteins such as fibronectin type III, pfam00041, and
Meprin, A5, mu (MAM), pfam00629, domains.
