Detergents are amphiphilic compounds that have crucial roles in the extraction, purification and stabilization of integral membrane proteins and in experimental studies of their structure and function. One technique that is highly dependent on detergents for solubilization of membrane proteins is solution-state NMR spectroscopy, where detergent micelles often serve as the best membrane mimetic for achieving particle sizes that tumble fast enough to produce high-resolution and high-sensitivity spectra, although not necessarily the best mimetic for a biomembrane. For achieving the best quality NMR spectra, detergents with partial or complete deuteration can be used, which eliminate interfering proton signals coming from the detergent itself and also eliminate potential proton relaxation pathways and strong dipole-dipole interactions that contribute line broadening effects. Deuterated detergents have also been used to solubilize membrane proteins for other experimental techniques including small angle neutron scattering and single-crystal neutron diffraction and for studying membrane proteins immobilized on gold electrodes. This is a review of the properties, chemical synthesis and applications of detergents that are currently commercially available and/or that have been synthesized with partial or complete deuteration. Specifically, the detergents are sodium dodecyl sulphate (SDS), lauryldimethylamine-oxide (LDAO), n-octyl-β-D-glucoside (β-OG), n-dodecyl-β-D-maltoside (DDM) and fos-cholines including dodecylphosphocholine (DPC). The review also considers effects of deuteration, detergent screening and guidelines for detergent selection. Although deuterated detergents are relatively expensive and not always commercially available due to challenges associated with their chemical synthesis, they will continue to play important roles in structural and functional studies of membrane proteins, especially using solution-state NMR.

用于膜蛋白结构和功能研究的氘代去污剂:性质,化学合成和应用。

洗涤剂是两亲性化合物,它们在完整膜蛋白的提取,纯化和稳定化及其结构和功能的实验研究中具有至关重要的作用。溶液状态NMR光谱法是一种高度依赖去污剂的技术,溶液状态NMR光谱学认为,去污剂胶束通常是最佳的膜模拟物,其粒径足以快速翻滚以产生高分辨率和高灵敏度的光谱,尽管不一定是生物膜的最佳模拟物。为了获得最佳质量的NMR光谱,可以使用部分或完全氘化的去污剂,它消除了来自去污剂本身的干扰质子信号,还消除了潜在的质子弛豫途径和强大的偶极-偶极相互作用,从而有助于谱线加宽。氘化去污剂还用于溶解膜蛋白,用于其他实验技术,包括小角度中子散射和单晶中子衍射,以及用于研究固定在金电极上的膜蛋白。这是对目前可商购的和/或已部分或完全氘化合成的去污剂的性质,化学合成和应用的综述。具体而言,去污剂是十二烷基硫酸钠(SDS),月桂基二甲胺氧化物(LDAO),氘化去污剂还用于溶解膜蛋白,用于其他实验技术,包括小角度中子散射和单晶中子衍射,以及用于研究固定在金电极上的膜蛋白。这是对目前可商购的和/或已部分或完全氘化合成的去污剂的性质,化学合成和应用的综述。具体而言,去污剂是十二烷基硫酸钠(SDS),月桂基二甲胺氧化物(LDAO),氘化去污剂还用于溶解膜蛋白,用于其他实验技术,包括小角度中子散射和单晶中子衍射,以及用于研究固定在金电极上的膜蛋白。这是对目前可商购的和/或已部分或完全氘化合成的去污剂的性质,化学合成和应用的综述。具体而言,去污剂是十二烷基硫酸钠(SDS),月桂基二甲胺氧化物(LDAO),目前可商购和/或已部分或完全氘化合成的去污剂的化学合成和应用。具体而言,去污剂是十二烷基硫酸钠(SDS),月桂基二甲胺氧化物(LDAO),目前可商购和/或已部分或完全氘化合成的去污剂的化学合成和应用。具体而言,去污剂是十二烷基硫酸钠(SDS),月桂基二甲胺氧化物(LDAO),辛基-β- D-葡糖苷(β-OG),十二烷基-β- D-麦芽糖苷(DDM)和磷胆碱,包括十二烷基磷酸胆碱(DPC)。审查还考虑了氘化,去污剂筛选和去污剂选择指南的影响。尽管氘化洗涤剂相对昂贵并且由于与其化学合成相关的挑战而并非总是可商购,但它们将继续在膜蛋白的结构和功能研究中发挥重要作用,尤其是使用溶液态NMR。
