Understanding the ice recrystallization inhibition (IRI) mechanism is of fundamental importance for the rational design of novel antifreeze protein mimetics and reducing IR-related damage. In this communication, using quantitive experimental methods and molecular dynamics simulations we demonstrate that zwitterionic poly(carboxybetaine methacrylate) (PCBMA) can serve as a novel IRI-active substance. This work unravels the atomic-level details of the IRI mechanism of zwitterionic antifreeze protein mimetics and provides insight into the development of next-generation antifreeze protein mimetics.
了解冰重结晶抑制(IRI)机制对于合理设计新型抗冻蛋白模拟物和减少与IR相关的损伤至关重要。在本通讯中,我们使用定量实验方法和分子动力学模拟证明两性离子聚(甲基丙烯酸羧基甜菜碱)(PCBMA)可作为一种新型的IRI活性物质。这项工作揭示了两性离子抗冻蛋白模拟物IRI机制的原子水平细节,并为下一代抗冻蛋白模拟物的开发提供了见解。
