This brief discusses the mechanism of functional expression of a
protein or protein complex utilizing the ATP hydrolysis cycle or
proton-motive force from a unique point of view focused on the
roles of water. A variety of processes are considered such as the
unidirectional movement of a linear-motor protein along a filament,
insertion of an unfolded protein into a chaperonin and release of
the folded protein from it, transport of diverse substrates across
the membrane by a transporter, and directed rotation of the central
subunit within a rotatory motor protein complex. These topics are
discussed in a unified manner within the same theoretical
framework. The author argues that water plays imperative roles in
the functional expression of these molecular machines. A pivotal
factor is the entropic force or potential originating from the
translational displacement of water molecules coexisting with the
molecular machines in the entire system.
