Abstract We introduce the use of multiple receivers applied in parallel for simultaneously recording multi-dimensional data sets of proteins in a single experiment. The utility of the approach is established through the introduction of the 2D 15N,1HN||13CO HSQC experiment in which a pair of two-dimensional 15N,1HN and 15N,13CO spectra are recorded. The methodology is further extended to higher dimensionality via the 3D 1HN||13CO HNCA in which a pair of data sets recording 13Cα,15N,1HN and 13Cα,15N,13CO chemical shifts are acquired. With the anticipated increases in probe sensitivity it is expected that multiple receiver experiments will become an important approach for efficient recording of NMR data.

Simultaneous acquisition of PAR and PAIN spectra
Simultaneous acquisition of PAR and PAIN spectra
Abstract We present a scheme that allows the simultaneous detection of PAR and PAIN correlation spectra in a single two-dimensional experiment. For both spectra, we obtain almost the same signal-to-noise ratio as if a PAR or PAIN spectrum is recorded separately, which in turn implies that one of the spectra may be considered additional information for free. The experiment is based on the observation that in a PAIN experiment, the PAR condition is always also fulfilled. The performance is demonstrated experimentally using uniformly...

Most multi-dimensional solution NMR experiments connect one dimension to another using coherence transfer steps that involve evolution under scalar couplings. While experiments of this type have been a boon to biomolecular NMR the need to work on ever larger systems pushes the limits of these procedures. Spin relaxation...

Three-dimensional HNCO and HNCA subspectra from a small protein (agitoxin, 4 kDa, enriched in carbon-13 and nitrogen-15), have been obtained by direct frequency-domain excitation of selected carbon and nitrogen sites. This new technique applies an array of several simultaneous soft radiofrequency spin-inversion pulses, encoded (on or off) according to nested Hadamard matrices, and the...

Resonance assignment of intrinsically disordered proteins is made difficult by the extensive spectral overlaps. High-resolution 3D and 4D spectra are thus essential for this purpose. We have adapted the series of 3D BEST experiments proposed by Lescop et al to the case of unfolded proteins. Longer acquisitions...
