Weak and Transient Protein Interactions Determined by Solid-State NMR

David Lyndon Emsley

Despite their roles in controlling many cellular processes, weak and transient interactions between large structured macromolecules and disordered protein segments cannot currently be characterized at atomic resolution by Xray crystallography or solution N ...

Structure and Mechanism of the Influenza A M2(18-60) Dimer of Dimers

David Lyndon Emsley

We report a magic angle spinning (MAS) NMR structure of the drug-resistant S31N mutation of M2(18-60) from Influenza A. The protein was dispersed in diphytanoyl-sn-glycero-3-phosphocholine lipid bilayers, and the spectra and an extensive set of constraints ...

Nanosecond Time Scale Motions in Proteins Revealed by High-Resolution NMR Relaxometry

Geoffrey Bodenhausen, Fabien Ferrage

Understanding the molecular determinants underlying protein function requires the characterization of both structure and dynamics at atomic resolution. Nuclear relaxation rates allow a precise characterization of protein dynamics at the Larmor frequencies ...

Method for nuclear magnetic resonance (NMR) spectroscopy measurements using long-lived coherences (LLC)

Geoffrey Bodenhausen, Paul Romeo Vasos, Riddhiman Sarkar, Puneet Ahuja

A method for nuclear magnetic resonance (NMR) spectroscopy of a sample comprises preparation of the sample and carrying out an NMR spectroscopy measurement. Preparation includes excitation of long lived coherences (LLC) between the singlet state S0 and the ...

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 ...

Analysis of sensitivity enhancement by dynamic nuclear polarization in solid-state NMR: a case study of functionalized mesoporous materials

Geoffrey Bodenhausen, Diego Carnevale

We systematically studied the enhancement factor (per scan) and the sensitivity enhancement (per unit time) in C-13 and Si-29 cross-polarization magic angle spinning (CP-MAS) NMR boosted by dynamic nuclear polarization (DNP) of functionalized mesoporous si ...

Royal Society of Chemistry2013

We introduce a new approach to improve structural and dynamical determination of large metalloproteins using solid-state nuclear magnetic resonance (NMR) with H-1 detection under ultrafast magic angle spinning (MAS). The approach is based on the rapid and ...

NATL ACAD SCIENCES2012

Pseudocontact shifts (PCSs) arise in para-magnetic systems in which the susceptibility tensor is anisotropic. PCSs depend upon the distance from the paramagnetic center and the position relative to the susceptibility tensor, and they can be used as structu ...

H-1, C-13 and N-15 resonance assignment of a 114-residue fragment of Engrailed 2 homeoprotein, a partially disordered protein

Geoffrey Bodenhausen, Fabien Ferrage

Engrailed 2 is a transcription factor belonging to the class of homeoproteins. These proteins possess a 60-residue DNA binding globular domain and play an important role in the early stages of development. We expressed and purified a 13.4 kDa fragment of E ...
