[NMR paper] Translational Diffusion and Self-Association of an Intrinsically Disordered Protein kappa-Casein Using NMR with Ultra-High Pulsed-Field Gradient and Time-Resolved FRET
Translational Diffusion and Self-Association of an Intrinsically Disordered Protein kappa-Casein Using NMR with Ultra-High Pulsed-Field Gradient and Time-Resolved FRET
Much attention has been given to studying the translational diffusion of globular proteins, whereas the translational diffusion of intrinsically disordered proteins (IDPs) is less studied. In this study, we investigate the translational diffusion and how it is affected by the self-association of an IDP, ?-casein, using pulsed-field gradient nuclear magnetic resonance and time-resolved Förster resonance energy transfer. Using...

[NMR paper] Early events in amyloid-? self-assembly probed by time-resolved solid state NMR and light scattering
Early events in amyloid-? self-assembly probed by time-resolved solid state NMR and light scattering
Self-assembly of amyloid-? peptides leads to oligomers, protofibrils, and fibrils that are likely instigators of neurodegeneration in Alzheimer's disease. We report results of time-resolved solid state nuclear magnetic resonance (ssNMR) and light scattering experiments on 40-residue amyloid-? (A?40) that provide structural information for oligomers that form on time scales from 0.7 ms to 1.0 h after initiation of self-assembly by a rapid pH drop. Low-temperature ssNMR spectra of...
[NMR paper] Surface Accessibility of an Intrinsically Disordered Protein Probed by 2D Time-Resolved Laser-Assisted NMR Spectroscopy
Surface Accessibility of an Intrinsically Disordered Protein Probed by 2D Time-Resolved Laser-Assisted NMR Spectroscopy
Probing the protein surface accessibility of different residues is a powerful way of characterizing the overall conformation of intrinsically disordered proteins (IDPs). We present a two-dimensional (2D) time-resolved photo-CIDNP (TR-CIDNP) experiment suitable for IDP analysis. Pulse stretching of high-power laser pulses, band-selective decoupling of ^(13)C^(?), and simultaneous application of radiofrequency and laser pulses were implemented to quantitatively analyze the...
