Side-chain to backbone correlations from solid-state NMR of perdeuterated proteins through combined excitation and long-range magnetization transfers
Side-chain to backbone correlations from solid-state NMR of perdeuterated proteins through combined excitation and long-range magnetization transfers
Abstract Proteins with excessive deuteration give access to proton detected solid-state NMR spectra of extraordinary resolution and sensitivity. The high spectral quality achieved after partial proton back-exchange has been shown to start a new era for backbone assignment, protein structure elucidation, characterization of protein dynamics, and access to protein parts undergoing motion. The large absence of protons at non-exchangeable...

Recovering lost magnetization: polarization enhancement in biomolecular NMR
Recovering lost magnetization: polarization enhancement in biomolecular NMR
Abstract Experimental sensitivity remains a major drawback for the application of NMR spectroscopy to fragile and low concentrated biomolecular samples. Here we describe an efficient polarization enhancement mechanism in longitudinal-relaxation enhanced fast-pulsing triple-resonance experiments. By recovering undetectable 1H polarization originating from longitudinal relaxation during the pulse sequence, the steady-state 15N polarization becomes enhanced by up to a factor of ~5 with respect to thermal...
