Although macromolecules have been traditionally described in terms of rigid and unique three-dimensional structures, the dynamics of these molecules have become increasingly important in the understanding the relationships between structure and mechanism. It has been suggested that vibrational modes in macromolecules may act, for example, to channel energy from the solvent to the active site of an enzyme to enable the reaction pathway to proceed through the transition state. It has also been shown that the dynamics of a protein may be important in allowing the access of the substrate to enzyme and that changes in the vibrational modes may contribute to entropic terms affecting the free energy interactions.
