Increasing the Amphiphilicity of an Amyloidogenic Peptide Changes the β-Sheet Structure in the Fibrils from Antiparallel to Parallel
Autor: John J. Balbach, Robert Tycko, Stephen C. Meredith, David Gordon
Publikováno v: Biophysical Journal. 86:428-434
Solid-state NMR measurements have been reported for four peptides derived from beta-amyloid peptide Abeta(1-42): Abeta(1-40), Abeta(10-35), Abeta(16-22), and Abeta(34-42). Of these, the first two are predicted to be amphiphilic and were reported to f

Measurement of dipole-coupled lineshapes in a many-spin system by constant-time two-dimensional solid state NMR with high-speed magic-angle spinning
Autor: John J. Balbach, Robert Tycko, Yoshitaka Ishii
Publikováno v: Chemical Physics. 266:231-236
A two-dimensional solid state NMR technique for measurements of dipole–dipole couplings in many-spin systems under high-speed magic-angle spinning (MAS) is described. The technique, called constant-time finite-pulse radio-frequency-driven recouplin

Publikováno v: Chemistry of Materials. 12:973-982
Nanocrystalline nickel aluminides (nano-NiAl and nano-Ni3Al) are synthesized by reactions of NiCl2 and LiAlH4 in Et2O or 1,3,5-trimethylbenzene, followed by annealing of the reaction products at 55...

We describe solid state NMR measurements on frozen solutions of the complex of the 24-residue HIV-1 gp120 V3 loop peptide RP135 with the Fab fragment of the anti-gp120 antibody 0.5β, using rotational echo double resonance (REDOR). In order to probe

Autor: D. S. Sibirtsev, John J. Balbach, Mark S. Conradi, Alexander V. Skripov, R. G. Barnes
Publikováno v: Physical Review B. 60:966-971
Nuclear magnetic resonance measurements of the {sup 45}Sc, {sup 1}H, and {sup 2}D spin-lattice relaxation rates in the solid solutions {alpha}-ScH{sub x} (x=0, 0.11, and 0.27) and {alpha}-ScD{sub x} (x=0.05 and 0.22) have been performed over the temp

Publikováno v: Physical Review B. 58:14823-14832
Three samples of ${\mathrm{YD}}_{x},$ with x ranging from 2.9 to nearly 3.0, were studied with deuterium nuclear magnetic resonance to gain insight into the locations of the D atoms in the lattice and their motions. Line shapes at low temperatures (2

Publikováno v: Chemical Physics Letters. 277:367-374
A new NMR technique is presented that yields high-resolution, 1-D NMR spectra of solutes in inhomogeneous magnetic fields. The method exploits the nuclear Overhauser effect which couples the longitudinal relaxation of solvent and solute nuclear spins
