[NMR paper] Optimal 13C NMR investigation of intrinsically disordered proteins at 1.2 GHz
Optimal 13C NMR investigation of intrinsically disordered proteins at 1.2 GHz
Nuclear magnetic resonance (NMR) spectroscopy is a powerful technique for characterizing biomolecules such as proteins and nucleic acids at atomic resolution. Increased magnetic field strengths drive progress in biomolecular NMR applications, leading to improved performance, e.g., higher resolution. A new class of NMR spectrometers with a 28.2 T magnetic field (1.2 GHz ¹H frequency) has been commercially available since the end of 2019. The availability of ultra-high-field NMR instrumentation...

[NMR paper] Exclusively heteronuclear NMR experiments for the investigation of intrinsically disordered proteins: focusing on proline residues
Exclusively heteronuclear NMR experiments for the investigation of intrinsically disordered proteins: focusing on proline residues
NMR represents a key spectroscopic technique that contributes to the emerging field of highly flexible, intrinsically disordered proteins (IDPs) or protein regions (IDRs) that lack a stable three-dimensional structure. A set of exclusively heteronuclear NMR experiments tailored for proline residues, highly abundant in IDPs/IDRs, are presented here. They provide a valuable complement to the widely used approach based on amide proton detection, filling the gap...

Investigation of Intrinsically Disordered Proteins through Exchange with Hyperpolarized Water
Hyperpolarized water can selectively enhance NMR signals of rapidly exchanging protons in osteopontin (OPN), a metastasis-associated intrinsically disordered protein (IDP), at near-physiological pH and temperature. The transfer of magnetization from hyperpolarized water is limited to solvent-exposed residues and therefore selectively enhances signals in 1H-15N correlation spectra. Binding to the polysaccharide heparin was found to induce the unfolding of preformed structural elements in OPN.A...
