Determination of the relative NH proton lifetimes of the peptide analogue viomycin in aqueous solution by NMR-based diffusion measurement

Autor: M, Liu, H C, Toms, G E, Hawkes, J K, Nicholson, J C, Lindon

Publikováno v: Journal of biomolecular NMR. 13(1)

In aqueous solution, exchanging peptide NH protons experience two environments, that of the peptide itself with a relatively slow diffusion coefficient and that of the water solvent with a faster diffusion coefficient. Although in slow exchange on th

Publikováno v: Magnetic resonance in chemistry : MRC. 46(4)

Solid-state (23)Na and (31)P magic-angle spinning nuclear magnetic resonance spectroscopy and X-ray crystallography have been used to study the structures of the chain metaphosphates NaCa(PO(3))(3) and NaSr(PO(3))(3). The compounds are isostructural

Thermodynamic origin of cis/trans isomers of a proline-containing beta-turn model dipeptide in aqueous solution: a combined variable temperature 1H-NMR, two-dimensional 1H,1H gradient enhanced nuclear Overhauser effect spectroscopy (NOESY), one-dimensional steady-state intermolecular 13C,1H NOE, and molecular dynamics study

Publikováno v: Biopolymers. 53(1)

The cis/trans conformational equilibrium of the two Ac-Pro isomers of the beta-turn model dipeptide [13C]-Ac-L-Pro-D-Ala-NHMe, 98% 13C enriched at the acetyl carbonyl atom, was investigated by the use of variable temperature gradient enhanced 1H-nmr,

88MHz 113Cd-n.m.r. studies of native rat liver metallothioneins

Autor: D E Holt, Peter J. Sadler, M Webb, K Cain, G E Hawkes, Jeremy K. Nicholson

Publikováno v: Scopus-Elsevier

Well-resolved 113Cd-n.m.r. spectra of 113Cd-induced rat liver metallothioneins 1 and 2 are obtainable even at 88 MHz (9.4T). The line-widths of resonances are not dominated by chemical-shift-anisotropy relaxation. The increased spectral dispersion wi
