Solid-State NMR Spectroscopy
A number of arylamides have been synthesized and found to exhibit potent antimicrobial activities against a broad spectrum of Gram-positive and Gram-negative bacteria while exhibiting low toxicity toward eukaryotic cells. These facially amphiphilic foldamers have a relatively rigid intramolecular hydrogen-bonded arylamide as a framework, which places trifluormethyl versus positively charged ami...
متن کاملCharacterization of Peek (polyaryletheretherketone) Polymers by Solid-state Nmr Spectroscopy
The family of poly(aryletherketone) or PAEK polymers are of great interest for extreme service environments in the oil and gas industry. These materials (PEEK’s, PEK’s, PEKEKK’s etc) are often used in environments of high pressures and temperatures, while being exposed to steam, water based drilling fluids or brines, or other corrosive chemical cocktails that are highly acidic, oxidizing or cau...
متن کاملStructural characterization of polyglutamine fibrils by solid-state NMR spectroscopy.
Protein aggregation via polyglutamine stretches occurs in a number of severe neurodegenerative diseases such as Huntington's disease. We have investigated fibrillar aggregates of polyglutamine peptides below, at, and above the toxicity limit of around 37 glutamine residues using solid-state NMR and electron microscopy. Experimental data are consistent with a dry fibril core of at least 70-80 Å ...
متن کاملAfterglow Solid-State NMR Spectroscopy.
Biomolecular solid-state NMR experiments have traditionally been collected through detection of 13C or 15N nuclei. Since these nuclei have relatively low sensitivity stemming from their smaller gyromagnetic ratios relative to 1H, the time required to collect multi-dimensional datasets serves as a limitation to resonance assignment and structure determination. One improvement in the field has be...
متن کاملIntermolecular Interactions and Protein Dynamics by Solid‐State NMR Spectroscopy
Understanding the dynamics of interacting proteins is a crucial step toward describing many biophysical processes. Here we investigate the backbone dynamics for protein GB1 in two different assemblies: crystalline GB1 and the precipitated GB1-antibody complex with a molecular weight of more than 300 kDa. We perform these measurements on samples containing as little as eight nanomoles of GB1. Fr...
