>gnl|CDD|238674 cd01378, MYSc_type_I, Myosin motor domain, type I myosins. Myosin I
generates movement at the leading edge in cell motility,
and class I myosins have been implicated in phagocytosis
and vesicle transport. Myosin I, 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.

>gnl|CDD|238682 cd01386, MYSc_type_XVIII, Myosin motor domain, type XVIII myosins.
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.

>gnl|CDD|233838 TIGR02366, DHAK_reg, probable dihydroxyacetone kinase regulator.
The seed alignment for this family was built from a set
of closely related uncharacterized proteins associated
with operons for the type of bacterial dihydroxyacetone
kinase that transfers PEP-derived phosphate from a
phosphoprotein, as in phosphotransferase system
transport, rather than from ATP. Members have a TetR
transcriptional regulator domain (pfam00440) at the
N-terminus and sequence homology throughout.

>gnl|CDD|132733 cd06935, NR_LBD_TR, The ligand binding domain of thyroid hormone
receptor, a members of a superfamily of nuclear
receptors. The ligand binding domain (LBD) of thyroid
hormone receptors: Thyroid hormone receptors are members
of a superfamily of nuclear receptors. Thyroid hormone
receptors (TR) mediate the actions of thyroid hormones,
which play critical roles in growth, development, and
homeostasis in mammals. They regulate overall metabolic
rate, cholesterol and triglyceride levels, and heart
rate, and affect mood. TRs are expressed from two
separate genes (alpha and beta) in human and each gene
generates two isoforms of the receptor through
differential promoter usage or splicing. TRalpha
functions in the heart to regulate heart rate and rhythm
and TRbeta is active in the liver and other tissues. The
unliganded TRs function as transcription repressors, by
binding to thyroid hormone response elements (TRE)
predominantly as homodimers, or as heterodimers with
retinoid X-receptors (RXR), and being associated with a
complex of proteins containing corepressor proteins.
Ligand binding promotes corepressor dissociation and
binding of a coactivator to activate transcription. Like
other members of the nuclear receptor (NR) superfamily
of ligand-activated transcription factors, TR has a
central well conserved DNA binding domain (DBD), a
variable N-terminal domain, a flexible hinge and a
C-terminal ligand binding domain (LBD).

and similar proteins, a subgroup of the CYTH-like
superfamily. CthTTM is a metal dependent
tripolyphosphatase, nucleoside triphosphatase, and
nucleoside tetraphosphatase. It hydrolyzes the
beta-gamma phosphoanhydride linkage of
triphosphate-containing substrates including
tripolyphosphate, nucleoside triphosphates and
nucleoside tetraphosphates. These substrates are
hydrolyzed, releasing Pi. Mg++ or Mn++ are required for
the enzyme's activity. CthTTM appears to have no
adenylate cyclase activity. This subgroup consists
chiefly of bacterial sequences. Members of the
CYTH-like (also known as triphosphate tunnel
metalloenzyme (TTM)-like) superfamily have a unique
active site located within an eight-stranded beta
barrel.
