The possible participation of protein fluctuation in enzyme activity is considered in this paper. Fluctuation is defined as vibrations, involving collective motion of a large number of atoms in protein molecules. Kinetic and thermodynamic aspects of protein fluctuation and enzyme-ligand interactions are discussed, paying special attention to the influence of electric fields and environmental microviscosity. A brief analysis of available experimental and theoretical data strongly suggests an interrelationship between protein fluctuation and enzyme function.
