A distinct mechanism of C-type inactivation in the Kv-like KcsA mutant E71V

open access: yesNature Communications, 2022
Constriction of the selectivity filter is assumed to be a hallmark of C-type inactivation in K+ channels. Using different high-resolution methods, this study shows a distinct C-type inactivation mechanism in a KcsA mutant that emulates Kv-channels.

Formation of the β-barrel assembly machinery complex in lipid bilayers as seen by solid-state NMR

open access: yesNature Communications, 2018
The β-barrel assembly machinery (BAM) catalyzes β-barrel protein insertion into the outer membrane of E.coli. Here authors employ high-sensitivity solid-state NMR to reveal how the lipid environment and formation of the BamA-BamCDE complex affect BamA ...

Regulation of the Target of Rapamycin and Other Phosphatidylinositol 3-Kinase-Related Kinases by Membrane Targeting

open access: yesMembranes, 2015
Phosphatidylinositol 3-kinase-related kinases (PIKKs) play vital roles in the regulation of cell growth, proliferation, survival, and consequently metabolism, as well as in the cellular response to stresses such as ionizing radiation or redox changes. In

A NMR guided approach for CsrA–RNA crystallization [PDF]

open access: yes, 2013
Structure determination of protein–nucleic acid complexes remains a challenging task. Here we present a simple method for generating crystals of a CsrA–nucleic acid complex, guided entirely by results from nuclear magnetic resonances spectroscopy (NMR ...

Atomic-level insight into mRNA processing bodies by combining solid and solution-state NMR spectroscopy

open access: yesNature Communications, 2019
Processing bodies are membrane less organelles that contain enzymes involved in mRNA turnover, among them enhancer of decapping 3 (Edc3). Here the authors use solid- and solution-state NMR spectroscopy to characterize the structural organization and ...

Characterization of the cell wall of a mushroom forming fungus at atomic resolution using solid-state NMR spectroscopy

open access: yesThe Cell Surface, 2020
Cell walls are essential in the interaction of fungi with the (a)biotic environment and are also key to hyphal morphogenesis and mechanical strength. Here, we used solid-state NMR (ssNMR) spectroscopy combined with HPLC and GC–MS to study the structural ...

Probing molecular motion by double-quantum (13C,13C) solid-state NMR spectroscopy: Application to ubiquitin [PDF]

open access: yes, 2010
We demonstrate the use of two-dimensional (13C,13C) double-quantum spectroscopy to detect molecular dynamics by solid-state NMR. Data collected on tyrosine-ethylester (TEE) are in line with previously determined (1H,13C) order parameters.

Characterization of a Cyclic Nucleotide-Activated K+ Channel and its Lipid Environment by Using Solid-State NMR Spectroscopy [PDF]

open access: yes, 2013
Voltage-gated ion channels are large tetrameric multidomain membrane proteins that play crucial roles in various cellular transduction pathways. Because of their large size and domain-related mobility, structural characterization has proved challenging ...

Probing Nuclear Dipole Moments and Magnetic Shielding Constants through 3-Helium NMR Spectroscopy

open access: yesPhyschem, 2022
Multinuclear NMR studies of the gaseous mixtures that involve volatile compounds and 3He atoms are featured in this review. The precise analyses of 3He and other nuclei resonance frequencies show linear dependencies on gas density.
