Ultrahigh‐Resolution NMR Spectroscopy [PDF]
Angewandte Chemie International Edition, 2014 All psyched up: A flexible and general pure shift experiment (PSYCHE) has been developed that offers superior sensitivity, spectral purity, and tolerance of strong coupling over existing methods for broadband homonuclear decoupling. The partial spectra of estradiol in [D6]DMSO obtained by normal 1H NMR spectroscopy and PSYCHE are shown for comparison.

Ruthenium Olefin Metathesis Catalysts Bearing Carbohydrate-Based N-Heterocyclic Carbenes [PDF]
, 2010 Ru-based olefin metathesis catalysts containing carbohydrate-derived NHCs from glucose and galactose were synthesized and characterized by NMR spectroscopy. 2D-NMR spectroscopy revealed the presence of Ru−C (benzylidene) rotamers at room temperature, and

Protein NMR spectroscopy [PDF]
Current Biology, 1998 Protein NMR spectroscopy does have its limitations. It has so far been used mainly for small proteins with molecular weight of less than 30 kDa, although a handful of publications have now reported the NMR study of proteins up to 40–50 kDa. Larger proteins typically have faster relaxation rates, which results in fatter NMR peaks that tend to merge with

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

Insight into Solvent Coordination of an Iron Porphyrin Hydroxylamine Complex from Spectroscopy and DFT Calculations [PDF]
, 2018 The reduction of Fe(OEP)(NO) in the presence of substituted phenols leads to a three‐electron reduction to form Fe(OEP)(NH2OH), which has been characterized by visible spectroscopy and electron stoichiometry.
