Probing Protein Dynamics Using Multifield Variable Temperature NMR Relaxation and Molecular Dynamics Simulation

David Lyndon Emsley, Albert Hofstetter, Nicola Salvi, Jayasubba Reddy Yarava, Baptiste Busi

Understanding the interplay between protein function and dynamics is currently one of the fundamental challenges of physical biology. Recently, a method using variable temperature solid-state nuclear magnetic resonance relaxation measurements has been prop ...

Cross-correlated relaxation measurements under adiabatic sweeps: determination of local order in proteins

Geoffrey Bodenhausen, Nicola Salvi, Pavel Kaderavek, Fabien Ferrage

Adiabatically swept pulses were originally designed for the purpose of broadband spin inversion. Later, unexpected advantages of their utilization were also found in other applications, such as refocusing to excite spin echoes, studies of chemical exchange ...

Challenges in preparing, preserving and detecting para-water in bulk: overcoming proton exchange and other hurdles

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Jonas Milani, Diego Carnevale, Nicola Salvi, Daniele Mammoli, Roberto Buratto, Estel Canet Martinez

Para-water is an analogue of para-hydrogen, where the two proton spins are in a quantum state that is antisymmetric under permutation, also known as singlet state. The populations of the nuclear spin states in para-water are believed to have long lifetimes ...

Distribution of Pico- and Nanosecond Motions in Disordered Proteins from Nuclear Spin Relaxation

Geoffrey Bodenhausen, Nicola Salvi, Fabien Ferrage

Intrinsically disordered proteins and intrinsically disordered regions (IDRs) are ubiquitous in the eukaryotic proteome. The description and understanding of their conformational properties require the development of new experimental, computational, and th ...

Theoretical tools for the design of NMR relaxation dispersion pulse sequences

Nicola Salvi

Recent decades have witnessed tremendous progress in the development of new experimental methods for studying biomolecules, particularly in the field of NMR relaxation dispersion. Here we review the theoretical frameworks that provided the insights necessa ...

Drug Screening Boosted by Hyperpolarized Long-Lived States in NMR

Geoffrey Bodenhausen, Sandrine Gerber, Aurélien Bornet, Jonas Milani, Sami Jannin, Basile Vuichoud, Solène Marcelle Françoise Marie Passemard, Nicola Salvi, Daniele Mammoli, Roberto Buratto

Transverse and longitudinal relaxation times (T11 and T1) have been widely exploited in NMR to probe the binding of ligands and putative drugs to target proteins. We have shown recently that long-lived states (LLS) can be more sensitive to ligand binding. ...

Solid-state carbon-13 NMR and computational characterization of the N719 ruthenium sensitizer adsorbed on TiO2 nanoparticles

Michael Graetzel, Geoffrey Bodenhausen, Diego Carnevale, Nicola Salvi, Julien Edouard Frey

The ruthenium-containing sensitizing dye N719 grafted on TiO2 nanoparticles was investigated by solidstate NMR. The carbon resonances are assigned by means of 13C cross-polarized dipolar dephasing experiments. DFT calculations of the carbon magnetic shield ...

Method for the nmr based determination of the affinity of drugs for a target protein

Geoffrey Bodenhausen, Aurélien Bornet, Nicola Salvi, Roberto Buratto

The document relates to a method for the determination of the binding properties of at least one first chemical compound to at least one second chemical compound between a free essentially dissociated state and a bound essentially associated state by using ...

Dynamic Studies through Control of Relaxation in NMR Spectroscopy

Nicola Salvi

In numerous biological processes that constitute the base of living organisms, protein function is fundamentally related to internal dynamics occurring on μs-ms time scales that can give rise to chemical exchange contributions to relaxation. In a heteronuc ...

Boosting the Sensitivity of Ligand-Protein Screening by NMR of Long-Lived States

Geoffrey Bodenhausen, Christian Heinis, Aurélien Bornet, Inmaculada Rentero Rebollo, Alessandro Angelini, Simone Ulzega, Nicola Salvi, Roberto Buratto

A new NMR method for the study of ligand protein interactions exploits the unusual lifetimes of long-lived states (LLSs). The new method provides better contrast between bound and free ligands and requires a protein-ligand ratio ca. 25 times lower than for ...
