We combine broadband dielectric spectroscopy (BDS) with 1H and 2H nuclear magnetic resonance (NMR) to study molecular dynamics in mixtures of ϵ-polylysine with H2O or D2O. In BDS, four relaxation processes can be attributed to molecular dynamics. Wh

It is well-accepted that hydration water is crucial for the structure, dynamics, and function of proteins. However, the exact role of water for the motions and functions of proteins is still debated. Experiments have shown that protein and water dyna

In glass-forming substances, the addition of water tends to produce the effect of lowering the glass transition temperature, T. In a previous work by some of us (Ruiz et al., Sci. Rep., 2017, 7, 7470) we reported on a rare anti-plasticizing effect of

Evidence of Coupling between the Motions of Water and Peptides

Autor: Silvina Cerveny, Izaskun Combarro-Palacios, Jan Swenson

Publikováno v: The journal of physical chemistry letters. 7(20)

Studies of protein dynamics at low temperatures are generally performed on hydrated powders and not in biologically realistic solutions of water because of water crystallization. However, here we avoid the problem of crystallization by reducing the s
