We present an approach that accelerates protein solid-state NMR 5-20-fold using paramagnetic doping to condense data-collection time (to approximately 0.2 s per scan), overcoming a long-standing limitation on slow recycling owing to intrinsic (1)H T(1) longitudinal spin relaxation. Using low-power schemes under magic-angle spinning at 40 kHz, we obtained(More)
We discuss a simple approach to enhance sensitivity for (13)C high-resolution solid-state NMR for proteins in microcrystals by reducing (1)H T(1) relaxation times with paramagnetic relaxation reagents. It was shown that (1)H T(1) values can be reduced from 0.4-0.8s to 60-70 ms for ubiquitin and lysozyme in D(2)O in the presence of 10 mM Cu(II)Na(2)EDTA(More)
