- Abstract
- Membrane proteins (MPs) are insoluble in aqueous media as a result of incompatibility between the hydrophilic property of the solvent molecules and the hydrophobic nature of MP surfaces, normally associated with lipid membranes. Amphipathic compounds are necessary for extraction of these macromolecules from the native membranes and their maintenance in solution. The amphipathic agents surround the hydrophobic segments of MPs, thus serving as a membrane mimetic system. Of the available amphipathic agents, detergents are most widely used for MP manipulation. However, MPs encapsulated by conventional detergent micelles have a tendency to undergo structural degradation, hampering MP advance, and necessitating the development of novel detergents with enhanced efficacy for MP study. In this chapter, we will introduce both conventional and novel classes of detergents and discuss about the chemical structures, design principles, and efficacies of these compounds for MP solubilization and stabilization. The behaviors of those agents toward MP crystallization will be a primary topic in our discussion. This discussion highlights the common features of popular conventional/novel detergents essential for successful MP structural study. The conclusions reached by this discussion would not only enable MP scientists to rationally select a set of detergent candidates among a large number of detergents but also provide detergent inventors with useful guidelines in designing novel amphipathic systems.
