Spinning faster: protein NMR at MAS frequencies up to 126Â*kHz
Spinning faster: protein NMR at MAS frequencies up to 126Â*kHz
Abstract
We report linewidth and proton T1, T1Ï? and T2â?² relaxation data of the model protein ubiquitin acquired at MAS frequencies up to 126Â*kHz. We find a predominantly linear improvement in linewidths and coherence decay times of protons with increasing spinning frequency in the range from 93 to 126Â*kHz. We further attempt to gain insight into the different contributions to the linewidth at fast MAS using site-specific analysis of proton relaxation parameters and present bulk...

Magic angle spinning (MAS) solid-state nuclear magnetic resonance (ssNMR) spectroscopy is a useful technique for structure determination, especially of membrane proteins. This method typically requires that protons in proteins be largely replaced with ...

Magic-angle spinning (MAS) is a technique that is a prerequisite for high-resolution solid-state NMR spectroscopy of proteins and other biomolecules. Recently, the 100kHz limit for the rotation frequency has been broken, arguably making MAS rotors the man-made objects with the highest rotation frequency. This development is expected to have a significant impact on biomolecular...

Sensitive 13Câ??13C correlation spectra of amyloid fibrils at very high spinning frequencies and magnetic fields
Abstract Sensitive 2D solid-state 13Câ??13C correlation spectra of amyloid β fibrils have been recorded at very fast spinning frequencies and very high magnetic fields. It is demonstrated that PARIS-xy recoupling using moderate rf amplitudes can provide structural information by promoting efficient magnetization transfer even under such challenging experimental conditions. Furthermore, it has been shown both experimentally and by numerical simulations that the method is not...
