Consider an ATP-driven molecular motor like myosin applying a force
on an actin cable in the cytoskeleton of the cell. Explain how the
concept of allostery could help understand the mechanism of such a
molecular motor.
Solutions
Expert Solution
Allosteric factors acts on molecular motors, and thereby effect
their functions. They binds other than the active site, but their
action is important in determining the function of molecular
motors.
The myosin cross-bridge cycle________.
requires ATP hydrolysis
involves interaction of myosin heads and the actin
filament
cannot occur if Ca++ is present
a and b
all of the above
Consider the actin-myosin contractile cycle. Based on this
cycle, explain how a decrease in myosin's ATPase activity could
affect muscle's ability to contract.
