Deuterium (²H) spin relaxation of ^(13)CH(2)D methyl groups has been widely applied to investigate picosecond-to-nanosecond conformational dynamics in proteins by solution-state NMR spectroscopy. The B(0) dependence of the ²H spin relaxation rates is represented by a linear relationship between the spectral density function at three discrete frequencies J(0), J(?(D)) and J(2?(D)). In this study, the linear relation between ²H relaxation rates at B(0) fields separated by a factor of two and the...

Partially-deuterated samples of HET-s(218â??289) fibrils: assignment and deuterium isotope effect
Partially-deuterated samples of HET-s(218â??289) fibrils: assignment and deuterium isotope effect
Abstract
Fast magic-angle spinning and partial sample deuteration allows direct detection of 1H in solid-state NMR, yielding significant gains in mass sensitivity. In order to further analyze the spectra, 1H detection requires assignment of the 1H resonances. In this work, resonance assignments of backbone HN and Hα are presented for HET-s(218â??289) fibrils, based on the existing assignment of Cα, Cβ, Câ??, and N resonances. The samples used are...
