Proteins as Machines
The following item discusses mechanical operations of motor proteins, microtubules, and other cytoskeleton-related structures:

Howard, J., Mechanics of Motor Proteins and the Cytoskeleton, Sunderland, Mass.:  Sinauer Associates, 2001, at page 1 states "Motor proteins are molecular machines." At page 3, Howard describes how microtubules can lead to mobility and force generation even without motor proteins.
