A novel deuterium-excited and proton-detected quadruple-resonance three-dimensional (3D) ²H(?)c(?)NH MAS nuclear magnetic resonance (NMR) method is presented to obtain site-specific ²H(?) deuterium quadrupolar couplings from protein backbone, as an extension to the 2D version of the experiment reported earlier. Proton-detection results in high sensitivity compared to the heteronuclei detection methods. Utilizing four independent radiofrequency (RF) channels (quadruple-resonance), we managed to...

Site-specific protein methyl deuterium quadrupolar patterns by proton-detected 3D 2Hâ??13Câ??1H MAS NMR spectroscopy
Abstract
Determination of protein structure and dynamics is key to understand the mechanism of protein action. Perdeuterated proteins have been used to obtain high resolution/sensitivty NMR experiments via proton-detection. These methods utilizes 1H, 13C and 15N nuclei for chemical shift dispersion or relaxation probes, despite the existing abundant deuterons. However, a high-sensitivity NMR method to utilize deuterons and e.g....

Determination of protein structure and dynamics is key to understand the mechanism of protein action. Perdeuterated proteins have been used to obtain high resolution/sensitivty NMR experiments via proton-detection. These methods utilizes ¹H, ^(13)C and ^(15)N nuclei for chemical shift dispersion or relaxation probes, despite the existing abundant deuterons. However, a high-sensitivity NMR method to utilize deuterons and e.g. determine site-specific deuterium quadrupolar...

Dynamic domains of amyloid fibrils can be site-specifically assigned with proton detected 3D NMR spectroscopy
Dynamic domains of amyloid fibrils can be site-specifically assigned with proton detected 3D NMR spectroscopy
Abstract
Several amyloid fibrils have cores framed by highly dynamic, intrinsically disordered, domains that can play important roles for function and toxicity. To study these domains in detail using solid-state NMR spectroscopy, site-specific resonance assignments are required. Although the rapid dynamics of these domains lead to considerable averaging of orientation-dependent NMR interactions and thereby line-narrowing, the proton...
