Understanding high pressure stability of helical conformation of oligopeptides and helix bundle protein high pressure FT-IR and RISM theoretical studies.
The pressure effect on conformational equilibria of simple organic compounds and the pressure denaturation of proteins have been well investigated by using vibrational spectroscopy. However, there was no systematic investigation of the pressure effect on conformational equilibria of oligopeptides, which are located between the simple organic compounds and proteins. Here, we review the recent vibrational spectroscopic and theoretical studies of the pressure effect on conformational equilibria of model oligopeptides and helix bundle protein in aqueous solution.
