NMR Studies of Membrane Structure and Dynamics
Over the past decade, there has been considerable interest in the motional state of the phospholipid bilayer membrane. The motivation underlying these efforts has been the contention that the phospholipid bilayer is the basic matrix in which membrane proteins are embedded to form the biological membrane, and that the permeability and mechanical properties of the membrane, as well as the enzymat...
متن کاملPhysical studies of cell surface and cell membrane structure. Deuterium nuclear magnetic resonance studies of N-palmitoylglucosylceramide (cerebroside) head group structure.
Deuterium Fourier-transform nuclear magnetic resonance spectra of N-palmitoyl[2,3,4,6,6-2H5]glucosylceramide, N-palmitoyl[1-2H]glucosylceramide, N-palmitoyl-[5,6,6-2H3]glucosylceramide, and N-palmitoyl[6,6-2H2]-glucosylceramide have been obtained at 55.3 MHz (corresponding to a magnetic field strength of 8.5 T) for lipids as multilamellar dispersions in excess water at 90 degrees C, above the g...
متن کاملThiogalactoside transacetylase. Physical and chemical studies of subunit structure.
The subunit size of thiogalactoside transacetylase from Escherichia coli ML 308 in 6 M guanidinium chloride measured by sedimentation equilibrium in the ultracentrifuge was found to be 29,700 =t 2,000, about half the molecular weight of the native protein. The two chains were identical by estimation of the number of peptides obtained after treatment with trypsin, BrCN, and with both reagents in...
متن کاملFundamental Structure/Property Studies of Gas Separation Membrane Polymers
Work in 2012-2013 focused on studying gas permeability, diffusivity and solubility of polyimides and thermally rearranged (TR) polymers based on 3,3’-dihydroxy-4,4’diaminobiphenyl (HAB) and 2,2’-bis-(3,4-dicarboxyphenyl) hexafluoropropane dianhydride (6FDA). To determine the effect of temperature on gas sorption, we studied H2 sorption in the HAB-6FDA polyimide and 3 partially converted HAB-6FD...
متن کاملPhysical studies of cell surface and cell membrane structure. Deuterium nuclear magnetic resonance investigation of deuterium-labelled N-hexadeconoylgalactosylceramides (cerebrosides).
1. Deuterium Fourier transform nuclear magnetic resonance spectra of a series of N-palmitoylgalactosylceramides (cerebrosides) specifically labelled with deuterium at one of positions 2', 6', 10' and 16' of the acyl chain, or in the C-6 hydroxymethyl group of the galactose residue, have been obtained using a spin-echo technique at 34.1 MHz with a homebuilt superconducting magnet spectrometer. 2...
