With the sensitivity enhancements conferred by dynamic nuclear polarization (DNP), magic angle spinning (MAS) solid state NMR spectroscopy experiments can attain the necessary sensitivity to detect very low concentrations of proteins. This potentially enables structural investigations of proteins at their endogenous levels in their biological contexts where their native stoichiometries with potential interactors is maintained. Yet, even with DNP, experiments are still sensitivity limited....

Detection of side-chain proton resonances of fully protonated biosolids in nano-litre volumes by magic angle spinning solid-state NMR
Abstract
We present a new solid-state NMR proton-detected three-dimensional experiment dedicated to the observation of protein proton side chain resonances in nano-liter volumes. The experiment takes advantage of very fast magic angle spinning and double quantum 13Câ??13C transfer to establish efficient (H)CCH correlations detected on side chain protons. Our approach is demonstrated on the HET-s prion domain in its...

Fast magic angle spinning NMR with heteronucleus detection for resonance assignments and structural characterization of fully protonated proteins
Fast magic angle spinning NMR with heteronucleus detection for resonance assignments and structural characterization of fully protonated proteins
Abstract
Heteronucleus-detected dipolar based correlation spectroscopy is established for assignments of 1H, 13C, and 15N resonances and structural analysis in fully protonated proteins. We demonstrate that 13C detected 3D experiments are highly efficient and permit assignments of the majority of backbone resonances, as shown in an 89-residue dynein light chain 8, LC8 protein. With these experiments, we...
