Using NMR diffusion data to validate MD models of disordered proteins: Test case of N-terminal tail of histone H4

Posted: 20.11.2023

Here, we investigate, both experimentally and via the MD modeling, the translational diffusion of a 25-residue N-terminal fragment from histone H4 (N-H4).

Effect of rotation in NMR diffusion experiments on micron-sized particles: A generalized theoretical treatment

Posted: 17.11.2022
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.
