| Research Abstract |
Existence of hyper-mobile water, whose motion is faster than that of bulk water, has been expected on the basis of the dielectric spectroscopy for the aqueous solution of molecular motors driven by ATP hydrolysis. The relation between the function of molecular motor and the hyper-mobile water has been discussed. We calculated the rotational and the dielectric time correlation functions of water around an ion on the basis of the trajectory of molecular dynamics simulation. The results showed that the water near by the ion gave fast dielectric relaxation although the rotational relaxation was slow. A new picture for hyper-mobile water was proposed. And we also calculated strong attractive interaction between two like-charged macroions immersed in electrolyte solution. The relation between ATP hydrolysis and treadmill motion of actins was discussed.
