Abstract :
Terahertz time-domain spectroscopy of a protein in a reverse micelle has been done as a function of the micelle size. The amplitude of its absorption is enhanced at a certain size of the micelle. This is explained in terms of the hydration effect of the protein which changes a hydrogen-bonded network not only between the protein and the surrounding water but also within the protein.
