Proteins are composed of l-amino acids, but nucleic acids and most oligosaccharides contain d-sugars as building blocks. It is interesting to ask whether this is a coincidence or a consequence of the functional interplay of these biomolecules. One reaction that provides an opportunity to study this interplay is the formation of phosphoramidate-linked peptido RNA from amino acids and ribonucleotides in aqueous condensation buffer. Here we report how the diastereoselectivity of the first peptide...
[NMR paper] Multiple-State Monitoring of SOD1 Amyloid Formation at Single-Residue Resolution by Rheo-NMR Spectroscopy
Multiple-State Monitoring of SOD1 Amyloid Formation at Single-Residue Resolution by Rheo-NMR Spectroscopy
Formation of protein aggregates or fibrils entails the conversion of soluble native protein monomers via multiple molecular states. No spectroscopic techniques have succeeded in capturing the transient molecular-scale events of fibrillation in situ. Here we report residue- and state-specific real-time monitoring of the fibrillation of amyotrophic lateral sclerosis-related SOD1 by rheology NMR (Rheo-NMR) spectroscopy. Under moderately denaturing conditions, where NMR signals of folded...

Aliphatic chain length by isotropic mixing (ALCHIM): determining composition of complex lipid samples by 1H NMR spectroscopy
Aliphatic chain length by isotropic mixing (ALCHIM): determining composition of complex lipid samples by 1H NMR spectroscopy
Abstract
Quantifying the amounts and types of lipids present in mixtures is important in fields as diverse as medicine, food science, and biochemistry. Nuclear magnetic resonance (NMR) spectroscopy can quantify the total amounts of saturated and unsaturated fatty acids in mixtures, but identifying the length of saturated fatty acid or the position of unsaturation by NMR is a daunting challenge. We have developed an NMR...
