  • Title: Crystallization of bacteriorhodopsin solubilized by a tripod amphiphile.
    Author: Theisen MJ, Potocky TB, McQuade DT, Gellman SH, Chiu ML.
    Journal: Biochim Biophys Acta; 2005 Aug 10; 1751(2):213-6. PubMed ID: 15963773.
    Abstract:
    Bacteriorhodopsin (bR) is solubilized efficiently as a monomer by a novel surfactant, a tripod amphiphile (TPA), which permits the formation of purple hexagonal bR crystals under several conditions. The crystals, although small, diffract to 2.5 A resolution using synchrotron radiation. TPA may be useful for the solubilization, purification, and crystallization of other membrane proteins.
