High-resolution microwave dielectric spectroscopy revealed that hyper-mobile water is induced around F-actin and increases upon binding with myosin S1.
High-resolution microwave dielectric spectroscopy reveals that hyper-mobile water is induced around F-actin and increases upon binding with myosin S1, providing clues to the molecular mechanism of muscle contraction.
No immediate clinical implications; hypothesis-generating for water dynamics in actin-myosin interactions.
A precision microwave dielectric spectroscopic technique has been developed. This technique enables us to analyze hydration properties of ions, proteins, and other biomolecules. φ-scan method gives an image of the information of spatial distribution of dielectric property of water surrounding protein molecules. Fixed φ analysis gives a direct comparison of hydration properties of different proteins. With this technique we analyzed the state change of F-actin hydration upon binding with myosin, and found that hyper-mobile water (HMW) is induced around F-actin and increased upon binding with myosin S1. Thus, we may obtain further information of collective properties of water surrounding proteins and biomolecules.

Suzuki et al. (2007) studied Muscle protein hydration (in vitro). Microwave dielectric spectroscopy (f-scan method) was evaluated on Dielectric property of water surrounding protein molecules. High-resolution microwave dielectric spectroscopy revealed that hyper-mobile water is induced around F-actin and increases upon binding with myosin S1.
