摘要：

The effects of heparin on the thermotropic properties of ferricytochrome c have been studied using high-sensitivity differential scanning calorimetry. Saturating concentrations of heparin at low ionic strength induced an important shift of the transition temperature T-m from 84.1 degrees C to 59.8 degrees C. This was accompanied by unusually large cooperativity of thermal denaturation of this complex, indicating strong intermolecular interactions between protein molecules. The destabilization of cytochrome c when mixed with heparin was not observed at high ionic strength, under which conditions complex was not formed.
