Influences of Low Energy Laser Beam on Fluctuation of Protein Conformation

Abstract

For the investigation of a possible mechanism causing the bio-effect of low energy laser beam, this paper describes the influences of the laser beam irradiationon protein conformation (spatial structure of a protein) relating to biological activation. Measurements of the myoglobin conformation are made by using the circular dichroism (CD) spectra, and the variation of the conformation is examined with respect to the irradiation time. The results show that the low energy laserbeam could promote the time fluctuation of the conformation content and might result in affecting the bio-effect.
