2H and 13C NMR studies on the temperature-dependent water and protein dynamics in hydrated elastin, myoglobin and collagen

TL;DR

This study uses 2H NMR techniques to investigate how water molecules in the hydration shells of elastin, myoglobin, and collagen change their dynamics with temperature, providing insights into protein-water interactions.

Contribution

It introduces a detailed 2H NMR analysis of hydration water dynamics across different proteins, highlighting temperature effects on molecular motion.

Findings

Water dynamics vary significantly with temperature in different proteins.

Hydration water exhibits distinct relaxation behaviors in elastin, myoglobin, and collagen.

The study enhances understanding of protein hydration and flexibility.

Abstract

2H NMR spin-lattice relaxation and line-shape analyses are performed to study the temperature-dependent dynamics of water in the hydration shells of myoglobin, elastin, and collagen.
