摘要：
Perturbation of thermal unfolding of cytochrome c with compression was investigated to obtain volumetric quantities of the unfolding. At pH 2.9-3.2 and around 40-60 degrees C, cytochrome c does not unfold but refold when compressed. This phenomenon contradicts to our present understanding that a protein unfolds if high pressure is applied. The volume change is strongly dependent on temperature and decreases with decreasing temperature. This change of volume changes its sign around 40 degrees C and is negative at room temperature.
