[Histone-heparin complexes].

W Roszkowska, K Worowski

    Acta Haematologica Polonica
    |October 1, 1979
    PubMed
    Summary

    Histones bind heparin, inhibiting its anticoagulant effects. Plasmin digestion breaks down these histone-heparin complexes, releasing active heparin.

    Area of Science:

    • Biochemistry
    • Pharmacology

    Context:

    • Histones are basic proteins that interact with nucleic acids.
    • Heparin is a widely used anticoagulant medication.
    • The interaction between histones and heparin has implications for drug efficacy and delivery.

    Purpose:

    • To investigate the interaction between histones and heparin.
    • To determine the effect of plasmin on histone-heparin complexes.
    • To assess the anticoagulant properties of histone degradation products.

    Summary:

    • Histones form insoluble complexes with heparin, neutralizing its anticoagulant activity.
    • Plasmin degrades histones, even those complexed with heparin.
    • The breakdown of histones within these complexes leads to the release of heparin, restoring its anticoagulant function.

    Impact:

    • Understanding histone-heparin interactions can inform the development of strategies to manage heparin efficacy.
    • This research sheds light on the potential for enzymatic degradation to modulate drug-protein complex activity.
    • Findings may guide the design of drug delivery systems involving protein-nucleic acid interactions.
