Here we investigate the conformational ensemble and interactions of the H4 tail in nucleosomes by means of solution NMR measurements of paramagnetic relaxation enhancements (PREs) in recombinant samples reconstituted with 15N-enriched H4 and nitroxide spin-label tagged H3.

Here we apply magic-angle spinning NMR, advanced phenylalanine 1H-13C/2H isotope labeling and MD simulation to a protein in three different crystal packing environments to shed light onto possible impact of packing on ring flips.

In this work, we have simulated diffraction photographs based on MD simulations of a supercell comprised of 125 unit cells of tetragonal lysozyme. The calculations were conducted using the fundamental Huygens–Fresnel principle.

A theory is developed to describe the effect of particle rotation in PFG NMR experiments. The rotation can produce 1.5-fold or even greater acceleration of apparent diffusion rates. Large macromolecular assemblies always diffuse much more slowly than their constituent monomers.
Version 22 of the Amber software suite represents a significant update from version 20.

The ability of nuclear spin singlet order (SO) to exhibit lifetimes much longer than spin lattice relaxation times has motivated the investigation into the use of such states as information or polarization storage vehicles. Potential applications include imaging, the study of slow kinetic or dynamic processes, or the study of weak relaxation mechanisms.
