Paper Abstract

The study of pressure-induced protein:protein interactions, and in particular the pressure-induced denaturation and dissociation of oligomeric proteins, has gained considerable interest in recent years. It is now well recognized that the protein transformation known under the general name of denaturation is a physical process which affects the three dimensional protein structure,leading to chain unfolding and/or refolding. Denaturation can be induced by changes in temperature or pressure, and by the addition of denaturing agents. The rationale for using pressure to study protein denaturation is that pressure variations at constant temperature only affect the volume of the protein, unlike the more commonly used temperature denaturation, which affects both the volume and the kinetic properties of the protein.
