• Mechanism of antifreeze protein functioning and the “anchored clathrate water” concept

  Publication

  • J. Zielkiewicz

  - JOURNAL OF CHEMICAL PHYSICS - Year 2023

  In liquid water, there is a natural tendency to form aggregates that consist of water molecules linked by hydrogen bonds. Such spontaneously formed aggregates are surrounded by a "sea" of disordered water molecules, with both forms remaining in equilibrium. The process of creating water aggregates also takes place in the solvation water of proteins, but in this case the interactions of water molecules with the protein surface shift...

  Badano właściwości pierwotnego kompleksu amfoterycyny B z ergosterolem przy pomocy symulacji dynamiki molekularnej. Otrzymane w wyniku naszych symulacji rezultaty słabo odpowiadają postulowanym przez innych autorów modelom kompleksu antybiotyk-sterol. Z drugiej strony uzyskane geometrie nie są sprzeczne z wynikami eksperymentów biofizycznych dotyczących powstawania kompleksów w wodzie i w środowisku wodno-alkoholowym.
