Sequence Modulates Polypeptoid Hydration Water Structure and Dynamics

Biomacromolecules, 2022
We use molecular dynamics simulations to investigate the effect of polypeptoid sequence on the structure and dynamics of its hydration waters. Polypeptoids provide an excellent platform to study small-molecule hydration in disordered polymers, as they can be precisely synthesized with a variety of sidechain chemistries. We examine water behavior near a

Hydration water in dynamics of a hydrated beta-lactoglobulin

The European Physical Journal Special Topics, 2007
Incoherent spin-echo signals of a hydrated β-lactoglobulin protein were investigated, at 275 and 293 K. The intermediate scattering functions I(Q,t) were divided in two contributions from surface water and protein, respectively. On one hand, the dynamics of the surface water follows a KWW stretched exponential function (the exponent is ~0.5), on the ...

Dynamics of hydration water in lysozyme

Physica B: Condensed Matter, 1997
Abstract We present quasi elastic incoherent neutron scattering data on a protein (lysozyme) wet powder at h = 0.45 (grams of water)/(grams of protein), corresponding to about a fully monolayer coverage of the protein surface. The data were collected under H2O and D2O hydration conditions; using the IRIS spectrometer with a resolution of 11 μeV. From

Glassy dynamics of water in hydrated cement paste

Applied Physics A: Materials Science & Processing, 2002
Understanding the state of the hydration water in cement and the ways to control it are likely to be the keys to the improvement of its ultimate strength and durability. In this study we investigate the diffusional dynamics of water molecules in hydrated tri-calcium silicate, a major component in ordinary Portland cement.

Glasslike dynamical behavior of the plastocyanin hydration water

Physical Review E, 2000
The dynamical behavior of water around plastocyanin has been investigated in a wide temperature range by molecular dynamics simulation. The mean square displacements of water oxygen atoms show, at long times, a t(alpha) trend for all temperatures. Below 150 K, alpha is constant and equal to 1; at higher temperatures it drops to a value significantly ...
