Closed model: NMR and X-rays open up enzyme clue

Date: Jul 1, 2017

Author: David Bradley

A structural model of the closed state of the "energy budget" enzyme adenylate kinase emerges from a nuclear magnetic resonance (NMR) spectroscopy and X-ray crystallography study by European scientists.

Stony coral: NMR and climate resistance

Date: Jun 15, 2017

Author: David Bradley

2D nuclear magnetic resonance (NMR) spectroscopy and ultra-high-resolution 3D imaging have been used to investigate a well-known and previously well-studied stony coral of the Indo-Pacific to reveal that it precipitates minerals through a biologically driven process. The findings suggest that this particular species may be more resistant to climate change than first thought.

Journal Highlight: Mutual diffusion driven NMR: a new approach for the analysis of mixtures by spatially resolved NMR spectroscopy

Date: Jun 6, 2017

Author: spectroscopyNOW

A new approach has been established for resolving the NMR spectra of mixtures, relying on the mutual diffusion of dissolved species when a concentration gradient is established within the NMR tube.

Nanosubmarine: NMR watches self destruction

Date: Jun 1, 2017

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy and other techniques have been used to characterise and observe the properties of a redox-sensitive stomatocyte nanomotor that could be used to deliver and release drugs directly to cells in the body.

Cellular signals: NMR metabolic profiling

Date: May 15, 2017

Author: David Bradley

A novel NMR technique developed by researchers at the University of Toronto Scarborough, Canada, can for the first time obtain undistorted high-resolution profiles of the molecules and metabolites present within a living organism.

Journal Highlight: Understanding surface and interfacial chemistry in functional nanomaterials via solid-state NMR

Date: May 1, 2017

Author: spectroscopyNOW

The use of solid-state NMR for the analysis of nanomaterials such as battery materials, nanocrystals, quantum dots, supramolecular assemblies, drug-delivery systems, ionomers and graphite oxides has been reviewed.

NMR reveals entropy redistribution: Bacterial proteins

Date: May 1, 2017

Author: David Bradley

Research carried out at the of the METACyt Biomolecular NMR Laboratory at IU Bloomington at Indiana University has revealed evidence that tiny changes in atomic movements in bacterial proteins can play a big role in how these microorganisms function and evolve.

NMR revision: Compound all at sea

Date: Apr 15, 2017

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy is a powerful tool and throws up chemical structure insights for even the most complex of natural products. Sometimes, however, those spectral lines can lead chemists to the wrong stereocentres and skeletons. An international team has now revised the structure of an important marine metabolite.

Journal Highlight: 'NMR Crystallization': in-situ NMR techniques for time-resolved monitoring of crystallization processes

Date: Apr 3, 2017

Author: spectroscopyNOW

An overview of the range of NMR strategies currently available for in-situ studies of crystallization processes is presented, with examples of applications that highlight their potential to deepen our understanding of crystallization phenomena.

Anemones punch holes: Toxins by NMR

Date: Apr 1, 2017

Author: David Bradley

A new approach to constructing a sea anemone toxin makes it plausible to incorporate site-specific isotopic labels for solid-state nuclear magnetic resonance (NMR) spectroscopic structural studies that will ultimately reveal how it functions and provide clues as to the action of other pore-forming proteins.
