Caenorhabditis elegans mut-7 and similar proteins. The
mut-7 subfamily is composed of Caenorhabditis elegans
mut-7 and similar proteins found in plants and
metazoans. Mut-7 is implicated in posttranscriptional
gene silencing. It contains a DEDDy-type DnaQ-like 3'-5'
exonuclease domain possessing three conserved sequence
motifs, termed ExoI, ExoII and ExoIII, with a specific

>gnl|CDD|176654 cd06142, RNaseD_exo, DEDDy 3'-5' exonuclease domain of Ribonuclease
D and similar proteins. Ribonuclease (RNase) D is a
bacterial enzyme involved in the maturation of small
stable RNAs and the 3' maturation of tRNA. It contains a
DEDDy-type DnaQ-like 3'-5' exonuclease domain possessing
three conserved sequence motifs termed ExoI, ExoII and
ExoIII, with a specific YX(3)D 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. In vivo,
RNase D only becomes essential upon removal of other
ribonucleases. Eukaryotic RNase D homologs include yeast
Rrp6p, human PM/Scl-100, and the Drosophila melanogaster
egalitarian protein.

>gnl|CDD|176653 cd06141, WRN_exo, DEDDy 3'-5' exonuclease domain of WRN and similar
proteins. WRN is a unique RecQ DNA helicase exhibiting
an exonuclease activity. It contains a DEDDy-type
DnaQ-like 3'-5' exonuclease domain possessing three
conserved sequence motifs termed ExoI, ExoII and ExoIII,
with a specific YX(3)D 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. Mutations in the
WRN gene cause Werner syndrome, an autosomal recessive
disorder associated with premature aging and increased
susceptibility to cancer and type II diabetes. WRN
interacts with key proteins involved in DNA replication,
recombination, and repair. It is believed to maintain
genomic stability and life span by participating in DNA
processes. WRN is stimulated by Ku70/80, an important
regulator of genomic stability.

responsible for the 3'-5' exonuclease proofreading
activity of E. coli DNA polymerase I (polI) and other
enzymes, it catalyzes the hydrolysis of unpaired or
mismatched nucleotides. This domain consists of the
amino-terminal half of the Klenow fragment in E. coli
polI it is also found in the Werner syndrome helicase
(WRN), focus forming activity 1 protein (FFA-1) and
ribonuclease D (RNase D). Werner syndrome is a human
genetic disorder causing premature aging; the WRN
protein has helicase activity in the 3'-5' direction.
The FFA-1 protein is required for formation of a
replication foci and also has helicase activity; it is a
homologue of the WRN protein. RNase D is a 3'-5'
exonuclease involved in tRNA processing. Also found in
this family is the autoantigen PM/Scl thought to be
involved in polymyositis-scleroderma overlap syndrome.

D, a 3'-exonuclease shown to act on tRNA both in vitro
and when overexpressed in vivo. Trusted members of this
family are restricted to the Proteobacteria; Aquifex,
Mycobacterial, and eukaryotic homologs are not

E. coli and is deleterious when overexpressed. Its

of family-A DNA polymerases, RNase D, WRN, and similar
proteins. DEDDy 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. They contain four invariant acidic
residues in three conserved sequence motifs termed ExoI,
ExoII and ExoIII. DEDDy exonucleases are classified as
such because of the presence of a specific YX(3)D
pattern at ExoIII. The four conserved acidic residues
serve as ligands for the two metal ions required for
catalysis. This family of DEDDy exonucleases includes
the proofreading domains of family A DNA polymerases, as
well as RNases such as RNase D and yeast Rrp6p. The
Egalitarian (Egl) and Bacillus-like DNA Polymerase I
subfamilies do not possess a completely conserved YX(3)D
pattern at the ExoIII motif. In addition, the
Bacillus-like DNA polymerase I subfamily has inactive
3'-5' exonuclease domains which do not possess the
metal-binding residues necessary for activity.

>gnl|CDD|176117 cd08426, PBP2_LTTR_like_5, The C-terminal substrate binding domain
of an uncharacterized LysR-type transcriptional
regulator, contains the type 2 periplasmic binding fold.
LysR-transcriptional regulators comprise the largest
family of prokaryotic transcription factor. Homologs of
some of LTTRs with similar domain organizations are also
found in the archaea and eukaryotic organisms. The LTTRs
are composed of two functional domains joined by a
linker helix involved in oligomerization: an N-terminal
HTH (helix-turn-helix) domain, which is responsible for
the DNA-binding specificity, and a C-terminal
substrate-binding domain, which is structurally
homologous to the type 2 periplasmic binding proteins.
As also observed in the periplasmic binding proteins,
the C-terminal domain of the bacterial transcriptional
repressor undergoes a conformational change upon
substrate binding which in turn changes the DNA binding
affinity of the repressor. The genes controlled by the
LTTRs have diverse functional roles including amino acid
biosynthesis, CO2 fixation, antibiotic resistance,
degradation of aromatic compounds, nodule formation of
nitrogen-fixing bacteria, and synthesis of virulence
factors, to a name a few. This substrate-binding domain
shows significant homology to the type 2 periplasmic
binding proteins (PBP2), which are responsible for the
uptake of a variety of substrates such as phosphate,
sulfate, polysaccharides, lysine/arginine/ornithine, and
histidine. The PBP2 bind their ligand in the cleft
between these domains in a manner resembling a Venus
flytrap. After binding their specific ligand with high
affinity, they can interact with a cognate membrane
transport complex comprised of two integral membrane
domains and two cytoplasmically located ATPase domains.
This interaction triggers the ligand translocation
across the cytoplasmic membrane energized by ATP
hydrolysis.

>gnl|CDD|238675 cd01379, MYSc_type_III, Myosin motor domain, type III myosins.
Myosin III has been shown to play a role in the vision
process in insects and in hearing in mammals. Myosin
III, an unconventional myosin, does not form dimers.
This catalytic (head) domain has ATPase activity and
belongs to the larger group of P-loop NTPases. Myosins
are actin-dependent molecular motors that play important
roles in muscle contraction, cell motility, and
organelle transport. The head domain is a molecular
motor, which utilizes ATP hydrolysis to generate
directed movement toward the plus end along actin
filaments. A cyclical interaction between myosin and
actin provides the driving force. Rates of ATP
hydrolysis and consequently the speed of movement along
actin filaments vary widely, from about 0.04 micrometer
per second for myosin I to 4.5 micrometer per second for
myosin II in skeletal muscle. Myosin II moves in
discrete steps about 5-10 nm long and generates 1-5
piconewtons of force. Upon ATP binding, the myosin head
dissociates from an actin filament. ATP hydrolysis
causes the head to pivot and associate with a new actin
subunit. The release of Pi causes the head to pivot and
move the filament (power stroke). Release of ADP
completes the cycle.
