An inter-laboratory comparison demonstrates that [H-1]-NMR metabolite fingerprinting is a robust technique for collaborative plant metabolomic data collection. [PDF]

, 2010
In any metabolomics experiment, robustness and reproducibility of data collection is of vital importance. These become more important in collaborative studies where data is to be collected on multiple instruments.

Shifts in the selectivity filter dynamics cause modal gating in K+ channels

Nature Communications, 2019
Spontaneous activity shifts at constant experimental conditions are widespread among ion channels but the molecular origins are poorly understood. Here, using solid-state NMR and MD simulations, the authors reveal that modal gating shifts in K + channels

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

Physchem, 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.

NMRFAM-SPARKY: enhanced software for biomolecular NMR spectroscopy

Bioinform., 2014
Summary: SPARKY (Goddard and Kneller, SPARKY 3) remains the most popular software program for NMR data analysis, despite the fact that development of the package by its originators ceased in 2001.

Biological solid-state NMR: Integrative across different scientific disciplines

Journal of Structural Biology: X, 2022
For almost five decades, solid-state NMR (ssNMR) has been used to study complex biomolecular systems. This article gives a view on how ssNMR methods and applications have evolved during this time period in a broader structural biology context.

Mode of action of teixobactins in cellular membranes

Nature Communications, 2020
The natural antibiotic teixobactin kills bacteria by direct binding to their cognate cell wall precursors (Lipid II and III). Here authors use solid-state NMR to reveal the native binding mode of teixobactins and show that teixobactins only weakly bind ...

Hyperpolarization-Enhanced NMR Spectroscopy with Femtomole Sensitivity Using Quantum Defects in Diamond [PDF]

Physical Review X, 2018
Nuclear magnetic resonance (NMR) spectroscopy is a widely used tool for chemical analysis and molecular structure identification. Because it typically relies on the weak magnetic fields produced by a small thermal nuclear spin polarization, NMR suffers ...

Binding of micro-nutrients to the cell wall of the fungus Schizophyllum commune

The Cell Surface, 2023
The cell wall fulfils several functions in the biology of fungi. For instance, it provides mechanical strength, interacts with the (a)biotic environment, and acts as a molecular sieve.

High-resolution NMR structure of an RNA model system : the 14-mer cUUCGg tetraloop hairpin RNA [PDF]

, 2010
We present a high-resolution nuclear magnetic resonance (NMR) solution structure of a 14-mer RNA hairpin capped by cUUCGg tetraloop. This short and very stable RNA presents an important model system for the study of RNA structure and dynamics using NMR ...

Structural Changes of Sodium Warfarin in Tablets Affecting the Dissolution Profiles and Potential Safety of Generic Substitution

Pharmaceutics, 2021
At present, the risk of generic substitutions in warfarin tablets is still being discussed. The aim of this study was to assess whether API interactions with commonly used excipients may affect the safety of generic replacement of warfarin sodium tablets.
