>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.
