Abstract

Three-legged friends: Intrinsic membrane proteins must usually be extracted from the native membrane with the aid of synthetic amphiphiles and then stabilized before detailed structural and functional characterization is possible. We describe new amphiphiles with unusual architectures that were useful for extraction and stabilization of protein superassemblies from bacterial membranes. Our results suggest that incorporation of branch points (as shown in figure) in both the hydrophilic and lipophilic portions can lead to favorable amphiphile behavior.
