based on deuteration in combination with dilution of the carbon spin system. The labeling
strategy achieves spectral editing by simplification of the HαCα and aliphatic side chain
spectral region. A reduction in both proton and carbon spin density in combination with fast
spinning (≥ 50 kHz) is essential to retrieve artifact-free 13C-R 1 relaxation data for aliphatic
carbons. We obtain good agreement between the NMR experimental data and order …
