Default Covariance spectroscopy in high-resolution multi-dimensional solid-state NMR.

Covariance spectroscopy in high-resolution multi-dimensional solid-state NMR.

Related Articles Covariance spectroscopy in high-resolution multi-dimensional solid-state NMR.

J Magn Reson. 2014 Feb;239:57-60

Authors: Lin EC, Opella SJ

Abstract
Covariance spectroscopy (COV), a statistical method that provides increased sensitivity, can be applied to two-dimensional high-resolution solid-state NMR experiments, such as homonuclear spin-exchange spectroscopy. We the alternative States sampling scheme to the experimental time by 50%. By combining COV with other processing methods for non-uniform sampling (NUS), many different three-dimensional experiments can be performed with substantial increases in overall sensitivity. As an example, we show a three-dimensional homonuclear spin-exchange/separated-local-field (SLF) spectrum that enables the assignment of resonances and the measurement of structural restraints from a single experiment performed in a limited amount of time.

Three-dimensional deuterium-carbon correlation experiments for high-resolution solid-state MAS NMR spectroscopy of large proteins
Three-dimensional deuterium-carbon correlation experiments for high-resolution solid-state MAS NMR spectroscopy of large proteins Abstract Well-resolved 2Hâ??13C correlation spectra, reminiscent of 1Hâ??13C correlations, are obtained for perdeuterated ubiquitin and for perdeuterated outer-membrane protein G (OmpG) from E. coli by exploiting the favorable lifetime of 2H double-quantum (DQ) states. Sufficient signal-to-noise was achieved due to the short deuterium T 1, allowing for high repetition rates and enabling 3D experiments with a 2Hâ??13C transfer step in a reasonable time....
