Characterization of the transverse relaxation rates in lipid bilayers.
The 2H NMR transverse relaxation rates of a deuterated phospholipid bilayer reflect slow motions in the bilayer membrane. A study of dimyristoyl lecithin specifically deuterated at several positions of the hydrocarbon chains indicates that these motions are cooperative and are confined to the hydrocarbon chains of the lipid bilayer. However, lipid head group interactions do play an important ro...
متن کاملDeuterium nuclear magnetic resonance studies of the interaction between dimyristoylphosphatidylcholine and gramicidin A'.
Deuterium nuclear magnetic resonance spectra of dimyristoylphosphatidylcholines (DMPCs) specifically labeled with deuterium at one of positions 2’, 3’, 4’, 6’, 8’, lo’, 12’, or 14’ of the 2-chain have been recorded at 34.1 MHz in the presence of varying concentrations of the linear pentadecapeptide antibiotic gramicidin A’. Deuterium quadrupole splittings (AvQ) have been used to partially chara...
متن کاملDeuterium NMR to study the surface of phospholipid bilayers
Deuterons placed specifically in the head-groups of phospholipids in bilayers were studied by H-NMR, which is a non-perturbing method for directly probing the conformation and dynamics of the deuterated segments at the bilayer surface. Information about the hydrationproperties ofphosphatidvlcholine bilayers was obtained by recording the spin-lattice (T;) relaxation times of DOPC-d. and DMPC-d9 ...
متن کاملSelective Protein-Lipid Interactions at Membrane Surfaces: A Deuterium and Phosphorus Nuclear Magnetic Resonance Study of the Association of Myelin Basic Protein with the Bilayer Head Groups of Dimyristoylphosphatidylcholine and Dimyristoylphosphatidylglycerolt
Basic protein from bovine spinal cord was reconstituted into bilayers of 1,2-dimyristoyl-sn-glycero-3phosphocholine, 1,2-dimyristoyl-sn-glycero-3-phospho-rucglycerol, and equimolar mixtures of both phospholipids at various protein concentrations up to 58 wt %. The lipids were selectively deuterated at all positions in their polar head groups, the motional rate and amplitude of which were charac...
متن کاملDeuterium spin probes of side-chain dynamics in proteins. 1. Measurement of five relaxation rates per deuteron in (13)C-labeled and fractionally (2)H-enriched proteins in solution.
New pulse sequences are presented for the measurement of the relaxation of deuterium double quantum, quadrupolar order, and transverse antiphase magnetization in (13)CH(2)D methyl groups of (15)N-, (13)C-labeled, fractionally deuterated proteins. Together with previously developed experiments for measuring deuterium longitudinal and transverse decay rates [Muhandiram, D. R.; Yamazaki, T.; Sykes...
