[Some peculiarities of trypsin and heparin interaction].
The interaction of trypsin with an acid polysaccharide, heparin, at pH 4.2 and 8.0 is studied. Heparin is found to destabilize the enzyme under condition of both autolytic denaturation (pH 8.0) and thermoinactivation (pH 4.2). Data on trypsin inactivation kinetics suggest that the stage of forming molecular complexes with different contents of trypsin and heparin precedes the stage of the enzyme denaturation. Maximal trypsin inactivation rate takes place under equimolar enzyme:heparin ration.
