The interpretation of entropy/enthalpy compensation phenomena in the deacylation of acyl-alpha-chymotrypsins.
The thermodynamic-compensation law observed for the deacylation of a series of acyl-alpha-chymotrypsins has been re-examined. From consideration of the effect of small changes in delta delta H+(+)delta T along a homologous series, it is suggested that the high Tc value of 420 K observed for the process has its origin in the solvation of the acyl-group-catalyst transition state.
