膜蛋白是许多生理和病理过程的关键。他们的研究通常涉及一个预先的去污剂溶解步骤,这会剥离膜,并可能危及膜蛋白的完整性。最近的去污剂替代品包括基于马来酸的共聚物(xMA),其破坏脂质双层并形成可溶于水性缓冲液的脂质蛋白纳米盘(xMALP)。虽然xMALP通常被称为天然纳米盘,但关于其脂质和蛋白质含量与天然双层的相似性知之甚少。在这里,我们分析了原核和真核xMALP使用脂质组学和凝胶内分析。我们的研究结果表明,xMALPs的含量随所用xMA的化学性质而变化。Barniol-Xicota和Verhelst研究了不同的马来酸基共聚物(xMA)在天然脂质环境中溶解膜蛋白的有用性。他们使用细菌和哺乳动物细胞系来研究不同的聚合物增溶效率,并专注于所得的蛋白质含量、蛋白质-脂质比和在xMA纳米颗粒内获得的脂质组成。
Membrane proteins are key in a large number of physiological and pathological processes. Their study often involves a prior detergent solubilization step, which strips away the membrane and can jeopardize membrane protein integrity. A recent alternative to detergents encompasses maleic acid based copolymers (xMAs), which disrupt the lipid bilayer and form lipid protein nanodiscs (xMALPs) soluble in aqueous buffer. Although xMALPs are often referred to as native nanodiscs, little is known about the resemblance of their lipid and protein content to the native bilayer. Here we have analyzed prokaryotic and eukaryotic xMALPs using lipidomics and in-gel analysis. Our results show that the xMALPs content varies with the chemical properties of the used xMA. Barniol-Xicota and Verhelst investigate the usefulness of different maleic acid-based copolymers (xMAs) to solubilize membrane proteins within native-like lipid environments. They use bacterial and mammalian cell lines to study different polymer solubilisation efficiencies and focus on resultant protein content, protein-lipid ratio, and the lipid compositions obtained within the xMA nanoparticles.
