The dynamics of spin-labeled lipid chains in the low-temperature phases of dipalmitoyl phosphatidylcholine (DPPC) membranes, with and without equimolar cholesterol, have been investigated by pulsed electron paramagnetic resonance (EPR) spectroscopy. Echo-detected spectra from the two-pulse, primary spin-echo (pulse sequence: π/2-τ-π-τ-echo) are used to detect rapid angular motions, on the time scale of the phase memory time (T 2 M ) that is in the nanosecond regime. Echo-detected spectra from… Expand

Librational motion of spin-labeled lipids in high-cholesterol containing membranes from echo-detected EPR spectra.
Two-pulse, echo-detected electron paramagnetic resonance (EPR) spectroscopy was used to study the librational motions of spin-labeled lipids in membranes of dipalmitoylphosphatidylcholine + 50 mol % cholesterol, which are important for glass-like states and are generally relevant to high lipid packing densities, e.g., in cholesterol-containing raft domains and condensed complexes.

Low-Temperature Dynamical Transition in Lipid Bilayers Detected by Spin-Label ESE Spectroscopy
Data on neutron scattering in biological systems show low-temperature dynamical transition between 170 and 230 K manifesting itself as a drastic increase of the atomic mean-squared displacement,Expand
Time-resolved electron spin resonance studies of spin-labelled lipids in membranes.
Two different applications of electron spin echo spectroscopy of spin-labelled phospholipids are reviewed, including the use of partially relaxed echo-detected ESR spectra to study the librational lipid-chain motions in the low-temperature phases of phospholIPid bilayers. Expand
Influence of Cholesterol on Molecular Motions in Spin-Labeled Lipid Bilayers Observed by Stimulated ESE
Electron spin echo (ESE) study was performed for spin-labeled lipids 1-palmitoyl-2-stearoyl-(5-d)-sn-glycero-3-phosphocholine in 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine phospholipid bilayer.Expand
X- and Q-Band Electron Spin Echo Study of Stochastic Molecular Librations of Spin Labels in Lipid Bilayers
Electron spin echo (ESE) of nitroxide spin labels allows detecting fast nanosecond stochastic restricted rotations (stochastic molecular librations), which is a common property of molecules inExpand
Backbone dynamics of alamethicin bound to lipid membranes: spin-echo electron paramagnetic resonance of TOAC-spin labels.
Electron spin-echo spectroscopy of alamethicin F50/5 analogs in which a selected Aib residue is replaced by the TOAC amino-acid spin label shows that torsional fluctuations of the peptide backbone take place on the subnanosecond to nanosecond timescale, with little temperature dependence. Expand
Molecular Motion in Frozen Phospholipid Bilayers in the Presence of Sucrose and Sorbitol Studied by the Spin-Echo EPR of Spin Labels
Electron spin echo (ESE) spectroscopy, a pulsed version of electron paramagnetic resonance (EPR), was applied to spin-labeled stearic acids in phospholipid bilayers hydrated in the presence ofExpand
Solvent effect on librational dynamics of spin-labelled haemoglobin by ED- and CW-EPR
Investigating the solvent effect on the librational motion of human haemoglobin spin-labelled on cysteine β93 with the nitroxide derivative of maleimide, 6-MSL finds evidence that solvent favours protein dynamics. Expand
Ether-linked lipids: Spin-label EPR and spin echoes.
D2O-ESEEM reveals that water exposure of the terminal methyl groups in the interdigitated phase of dihexadecyl phosphatidylcholine (DHPC) is comparable to that of the methylene groups at the polar head-group end of the chains. Expand
Communication: Orientational self-ordering of spin-labeled cholesterol analogs in lipid bilayers in diluted conditions.
Electro spin echo spectroscopy obtained data evidence that cholesterol molecules at low concentrations in biological membranes can interact via large distances of several nanometers which results in their orientational self-ordering. Expand
