>gnl|CDD|238673 cd01377, MYSc_type_II, Myosin motor domain, type II myosins. Myosin
II mediates cortical contraction in cell motility, and
is the motor in smooth and skeletal muscle. 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|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.

>gnl|CDD|176255 cd08295, double_bond_reductase_like, Arabidopsis alkenal double
bond reductase and leukotriene B4
12-hydroxydehydrogenase. This group includes proteins
identified as the Arabidopsis alkenal double bond
reductase and leukotriene B4 12-hydroxydehydrogenase.
The Arabidopsis enzyme, a member of the medium chain
dehydrogenase/reductase family, catalyzes the reduction
of 7-8-double bond of phenylpropanal substrates as a
plant defense mechanism. Prostaglandins and related
eicosanoids (lipid mediators involved in host defense
and inflamation) are metabolized by the oxidation of the
15(S)-hydroxyl group of the NAD+-dependent (type I
15-PGDH) 15-prostaglandin dehydrogenase (15-PGDH)
followed by reduction by NADPH/NADH-dependent (type II
15-PGDH) delta-13 15-prostaglandin reductase (13-PGR) to
15-keto-13,14,-dihydroprostaglandins. 13-PGR is a
bifunctional enzyme, since it also has leukotriene B(4)
12-hydroxydehydrogenase activity. Leukotriene B4 (LTB4)
can be metabolized by LTB4 20-hydroxylase in inflamatory
cells, and in other cells by bifunctional LTB4
12-HD/PGR. These 15-PGDH and related enzymes are members
of the medium chain dehydrogenase/reductase family. The
medium chain dehydrogenases/reductase
(MDR)/zinc-dependent alcohol dehydrogenase-like family,
which contains the zinc-dependent alcohol dehydrogenase
(ADH-Zn) and related proteins, is a diverse group of
proteins related to the first identified member, class I
mammalian ADH. MDRs display a broad range of activities
and are distinguished from the smaller short chain
dehydrogenases (~ 250 amino acids vs. the ~ 350 amino
acids of the MDR). The MDR proteins have 2 domains: a
C-terminal NAD(P) binding-Rossmann fold domain of an
beta-alpha form and an N-terminal catalytic domain with
distant homology to GroES.

>gnl|CDD|239263 cd02965, HyaE, HyaE family; HyaE is also called HupG and HoxO. They
are proteins serving a critical role in the assembly of
multimeric [NiFe] hydrogenases, the enzymes that
catalyze the oxidation of molecular hydrogen to enable
microorganisms to utilize hydrogen as the sole energy
source. The E. coli HyaE protein is a chaperone that
specifically interacts with the twin-arginine
translocation (Tat) signal peptide of the [NiFe]
hydrogenase-1 beta subunit precursor. Tat signal
peptides target precursor proteins to the Tat protein
export system, which facilitates the transport of fully
folded proteins across the inner membrane. HyaE may be
involved in regulating the traffic of [NiFe]
hydrogenase-1 on the Tat transport pathway.
