title: [Interaction of chondroitin sulfate with enzymes].
abstract: Chondroitin sulphate forms noncovalent electrostatic biocatalyst-glycosaminoglycan complexes in the solutions of enzymes. Chondroitin sulphate also interacts with enzymes developing complexes after carbodiimide activation of its carboxylic groups. Relatively low-molecular weight of biocatalysts (chymotrypsin, superoxide dismutase) forms stable noncovalent conjugates with the additional interaction as compared with electrostatic complexes. High-molecular weight of enzymes (acid phosphatase) develops covalent conjugates. Chondroitin sulphate is proposed for covalent binding of large proteins and multi-enzymatic complexes to obtain their stabilized derivatives for medical application.
