An osmolyte effect on the heat capacity change for protein folding.


Abstract

We have carried out a differential scanning calorimetry study into the pH effect on the thermal denaturation of ribonuclease A at several concentrations of the osmolyte sarcosine. In order to properly analyze these data, we have elaborated the thermodynamic theory of the linkage between temperature, cosolvent, and pH effects. The denaturation heat capacity increases with sarcosine concentration. The effects of temperature and sarcosine concentration on the denaturation enthalpy and entropy values are well described by convergence equations, with convergence temperatures of around 100 degrees C for the enthalpy and around 112 degrees C for the entropy; we suggest that these effects might be related to a solvent-induced alteration of the apolar-group-hydration contribution to the folding thermodynamics. From our data, we estimate that about 70 extra molecules of water are thermodynamically bound upon ribonuclease denaturation in diluted aqueous solutions of sarcosine; this number is 6-9 times smaller than that predicted on the basis of the following two premises: (a) the osmolyte is strongly excluded from the surface of both the native and the denatured protein and (b) the denatured state is a fully solvated chain. We suggest that at least one of these two premises does not hold. We briefly comment on the potential use of cosolvent effects on thermal denaturation to evaluate the degree of hydration of denatured proteins (thus providing an independent measure of the consequence of their possible residual structure) and, also, on the possibility of finding substances that are more efficient protein stabilizers than known osmolytes are.
