Area of Science:

  • Biochemistry and Molecular Biology
  • Glycobiology
  • Drug Discovery

Background:

  • Protein-carbohydrate interactions are fundamental to biological processes like signaling, recognition, and catalysis.
  • These interactions are crucial for understanding and treating diseases such as bacterial/fungal infections, cancer, and AIDS.
  • Heparin, a significant pharmaceutical, is of ongoing interest due to its role in binding phenomena and potential for developing selective anticoagulants.

Purpose of the Study:

  • To deepen the molecular-level understanding of protein-carbohydrate interactions.
  • To explore the therapeutic potential of targeting carbohydrate-processing enzymes (glycosyltransferases and glycosidases).
  • To investigate heparin's mechanisms of cross-reactivity and guide the development of safer anticoagulants.

Main Methods:

  • Analysis of molecular mechanisms underlying protein-carbohydrate binding.
  • Characterization of enzyme activity in oligosaccharide synthesis and breakdown.
  • Studies on heparin's structure-activity relationships and associated side effects.

Main Results:

  • Identified key protein-carbohydrate interactions driving biological functions.
  • Highlighted glycosyltransferases and glycosidases as critical targets for therapeutic intervention.
  • Elucidated mechanisms of heparin cross-reactivity, informing the design of selective anti-clotting agents.

Conclusions:

  • A comprehensive understanding of protein-carbohydrate interactions is essential for novel therapeutic development.
  • Targeting carbohydrate-processing enzymes and refining heparin-based drugs can address significant health challenges.
  • Further research into multivalent protein-carbohydrate interactions, like those involving bacterial toxins, will yield new therapeutic strategies.
