A pair of NMR experiments is developed for separation of individual fast-relaxing transitions inCH3methyl groups of methyl-protonated, highly deuterated proteins, and the measurement of their relaxation rates. Intra-methylH-H/H-C dipole-dipole cross-correlated spin relaxation that differentiates the rates of the fast-relaxing...

Selective 1H-13C NMR spectroscopy of methyl groups in residually protonated samples of large proteins
Selective 1H-13C NMR spectroscopy of methyl groups in residually protonated samples of large proteins
Abstract Methyl 13CHD2 isotopomers of all methyl-containing amino-acids can be observed in residually protonated samples of large proteins obtained from -glucose/D2O-based bacterial media, with sensitivity sufficient for a number of NMR applications. Selective detection of some subsets of methyl groups (Alaβ, Thrγ2) is possible using simple â??out-and-backâ?? NMR methodology. Such selective methyl-detected â??out-and-backâ?? NMR experiments allow complete assignments of threonine γ2...

Studying protein components of large intracellular complexes by in-cell NMR has so far been impossible because the backbone resonances are unobservable due to their slow tumbling rates. We describe a methodology that overcomes...

Abstract:
MAS solid-state NMR experiments applied to biological solids are still hampered by low sensitivity and resolution. In this work, we employ a deuteration scheme in which individual methyl groups are selectively protonated. This labeling scheme...
