Estimating side-chain order in methyl-protonated, perdeuterated proteins via multiple-quantum relaxation violated coherence transfer NMR spectroscopy
Abstract Relaxation violated coherence transfer NMR spectroscopy (Tugarinov et al. in J Am Chem Soc 129:1743â??1750, 2007) is an established experimental tool for quantitative estimation of the amplitudes of side-chain motions in methyl-protonated, highly deuterated proteins. Relaxation violated coherence transfer experiments monitor the build-up of methyl proton multiple-quantum coherences that can be created in magnetically equivalent...

Simultaneous acquisition of 13Cαâ??15N and 1Hâ??15Nâ??15N sequential correlations in proteins: application of dual receivers in 3D HNN
Abstract We describe here, adaptation of the HNN pulse sequence for multiple nuclei detection using two independent receivers by utilizing the detectable 13Cα transverse magnetization which was otherwise dephased out in the conventional HNN experiment. It enables acquisition of 2D 13Cαâ??15N sequential correlations along with the standard 3D 15Nâ??15Nâ??1H correlations, which provides directionality to sequential walk in HNN, on one hand, and enhances...

Authors: Kup?e E
Parallel acquisition NMR spectroscopy (PANSY) is used to detect simultaneously signals from up to four nuclear species, such as H-1, H-2, C-13, N-15, F-19 and P-31. The conventional COSY, TOCSY, HSQC, HMQC and HMBC pulse sequences have been adapted for such applications. Routine availability of NMR systems that incorporate multiple receivers has led to development of new types of NMR experiments. One such scheme named PANACEA allows unambiguous...

Sensitivity enhancement in liquid state nuclear magnetic resonance (NMR) triple resonance experiments for the sequential assignment of proteins is important for the investigation of large proteins or protein complexes. We present here the 3D TROSY-MQ/CRINEPT-HN(CO)CA which makes...

We show that the weak signal that remains after (13)C-detected experiments (the (13)C "afterglow") can still be measured with high sensitivity by proton detection. This is illustrated by the incorporation of two experiments, 2D (HA)CACO and 3D (HA)CA(CO)NNH, into a single pulse sequence that makes use of two receivers...
