We test the performance of several 13C homonuclear mixing sequences on perdeuterated microcrystalline ubiquitin. All sequences were applied without 1H decoupling and at relatively low MAS frequencies. We found that RFDR gave the highest overall transfer efficiency and that DREAM performs surprisingly well under these conditions being twice as efficient in the aliphatic region of the spectrum than the other mixing sequences tested.

Backbone assignment of perdeuterated proteins using long-range H/C-dipolar transfers
Backbone assignment of perdeuterated proteins using long-range H/C-dipolar transfers
Abstract For micro-crystalline proteins, solid-state nuclear magnetic resonance spectroscopy of perdeuterated samples can provide spectra of unprecedented quality. Apart from allowing to detect sparsely introduced protons and thereby increasing the effective resolution for a series of sophisticated techniques, deuteration can provide extraordinary coherence lifetimesâ??obtainable for all involved nuclei virtually without decoupling and enabling the use of scalar magnetization transfers. Unfortunately,...

Optimum levels of exchangeable protons in perdeuterated proteins for proton detection in MAS solid-state NMR spectroscopy
Optimum levels of exchangeable protons in perdeuterated proteins for proton detection in MAS solid-state NMR spectroscopy
Abstract We present a systematic study of the effect of the level of exchangeable protons on the observed amide proton linewidth obtained in perdeuterated proteins. Decreasing the amount of D2O employed in the crystallization buffer from 90 to 0%, we observe a fourfold increase in linewidth for both 1H and 15N resonances. At the same time, we find a gradual increase in the signal-to-noise ratio (SNR) for 1Hâ??15N correlations in dipolar coupling based experiments for...

The increase in dimensionality of three-dimensional (3D) NMR greatly enhances the spectral resolution in comparison to 2D NMR. It alleviates the problem of resonance overlap and may extend the range of molecules amenable to structure determination by...

Cell-free protein synthesis of perdeuterated proteins for NMR studies
Cell-free protein synthesis of perdeuterated proteins for NMR studies
Touraj Etezady-Esfarjani, Sebastian Hiller, Cristina Villalba and Kurt Wüthrich
Journal of Biomolecular NMR; 2007; 39(3); pp 229-238
Abstract:
Cell-free protein synthesis protocols for uniformly deuterated proteins typically yield low, non-uniform deuteration levels. This paper introduces an E. coli cell-extract, D-S30, which enables efficient production of proteins with high deuteration levels for all non-labile hydrogen atom positions. Potential applications of the new protocol may include production of proteins...

Journal of Biomolecular NMR; 2008; 40(4); pp 227-237
Abstract:
We have explored the design of broadband scalar coupling mediated 13C–13C and cross-relaxation suppressed 1H–1H TOCSY sequences employing phase/amplitude modulated inversion pulses. Considering a variety of supercycles, pulsewidths and a RF field strength of 10 kHz, the Fourier coefficients...
