洗涤剂通常用于从脂质双层中提取膜蛋白 (MP) 并将其保持在溶液中。然而,封装在洗涤剂胶束中的 MP 通常容易变性和聚集。因此,开发具有增强稳定特性的新型药剂对于推进 MP 研究是必要的。麦芽糖新戊二醇-3 (MNG-3) 已促成超过 10 种晶体结构,包括 G 蛋白偶联受体。在这里,我们制备了 MNG-3 类似物,并使用选定的 MP 表征了它们的特性。就膜蛋白稳定功效而言,大多数 MNG 的表现优于传统洗涤剂正十二烷基β-D-吡喃麦芽糖苷 (DDM)。有趣的是,根据目标 MP,使用不同的 MNG-3 类似物可实现最佳稳定性。这种去垢剂特异性的起源可以用一个新概念来解释:去垢剂疏水性与 MP 变性和聚集倾向之间的相容性。这套 MNG 代表了当前用于处理 MP 的去垢剂的可行替代品,并且也可以用作估计 MP 对变性和聚集的敏感性的工具。
Detergents are typically used to both extract membrane proteins (MPs) from the lipid bilayer and maintain them in solution. However, MPs encapsulated in detergent micelles are often prone to denaturation and aggregation. Thus, development of novel agents with enhanced stabilization characteristics is necessary to advance MP research. Maltose neopentyl glycol-3 (MNG-3) has contributed to >10 crystal structures including G-protein coupled receptors. Here we prepared MNG-3 analogues and characterised their properties using selected MPs. Most MNGs behaved superior to a conventional detergent, n–dodecyl–β–D–maltopyranoside (DDM), in terms of membrane protein stabilization efficacy. Interestingly, optimal stabilization was achieved with different MNG-3 analogues depending on the target MP. The origin for such detergent specificity could be explained by a novel concept: compatibility between detergent hydrophobicity and MP tendency to denature and aggregate. This set of MNGs represents viable alternatives to currently available detergents for handling MPs, and can be also used as tools to estimate MP sensitivity to denaturation and aggregation.
