A
protein with catalytic (enzymatic) activity that
converts the chemical energy
of adenosine triphosphate into mechanicalenergy to move along the surface of suitable
proteinaceous filamentous rails. The direction of its movements is strongly
related to both the intrinsic molecular
structure of the motor protein
and the polarity of the filament.
Motor
proteins are a class of molecular
motors that are able to move along the surface of a suitable substrate. They are powered by the hydrolysis of
ATP and convert chemical energy
into mechanicalwork.
