>gnl|CDD|238681 cd01385, MYSc_type_IX, Myosin motor domain, type IX myosins. Myosin
IX is a processive single-headed motor, which might play
a role in signalling. 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.

thioltransferases (disulfide reductases) which utilize
glutathione and NADPH as cofactors. Oxidized glutathione
is regenerated by glutathione reductase. Together these
components compose the glutathione system. Glutaredoxins
utilize the CXXC motif common to thioredoxins and are
involved in multiple cellular processes including
protection from redox stress, reduction of critical
enzymes such as ribonucleotide reductase and the
generation of reduced sulfur for iron sulfur cluster
formation. Glutaredoxins are capable of reduction of
mixed disulfides of glutathione as well as the formation
of glutathione mixed disulfides. This model represents
eukaryotic glutaredoxins and includes sequences from
fungi, plants and metazoans as well as viruses.

selenoprotein. This homodimeric, FAD-containing member
of the pyridine nucleotide disulfide oxidoreductase
family contains a C-terminal motif Cys-SeCys-Gly, where
SeCys is selenocysteine encoded by TGA (in some sequence
reports interpreted as a stop codon). In some members of
this subfamily, Cys-SeCys-Gly is replaced by
Cys-Cys-Gly. The reach of the selenium atom at the
C-term arm of the protein is proposed to allow broad
substrate specificity.

>gnl|CDD|239511 cd03419, GRX_GRXh_1_2_like, Glutaredoxin (GRX) family, GRX human
class 1 and 2 (h_1_2)-like subfamily; composed of
proteins similar to human GRXs, approximately 10 kDa in
size, and proteins containing a GRX or GRX-like domain.
GRX is a glutathione (GSH) dependent reductase,
catalyzing the disulfide reduction of target proteins
such as ribonucleotide reductase. It contains a redox
active CXXC motif in a TRX fold and uses a similar
dithiol mechanism employed by TRXs for intramolecular
disulfide bond reduction of protein substrates. Unlike
TRX, GRX has preference for mixed GSH disulfide
substrates, in which it uses a monothiol mechanism where
only the N-terminal cysteine is required. The flow of
reducing equivalents in the GRX system goes from NADPH
-> GSH reductase -> GSH -> GRX -> protein substrates. By
altering the redox state of target proteins, GRX is
involved in many cellular functions including DNA
synthesis, signal transduction and the defense against
oxidative stress. Different classes are known including
human GRX1 and GRX2, which are members of this
subfamily. Also included in this subfamily are the
N-terminal GRX domains of proteins similar to human
thioredoxin reductase 1 and 3.
