Studies of biological effects of high intensities static magnetic fields on the conformation and activity of vitro catalase in bovine liver

ZHANG Jun, SHUN Fan, CHEN De-wan, et al. (University of ChongQin Medical Sciences, Dep. of biology, ChongQin 400016, China)  
purpose: Studied the effects of static magnetic fields on vitro catalase's conformation and activity, method: After the natural enzyme was exposed under various intensities of magnetic fields for a certain period of time, got it out of magnetic fields at once , then analyzed its spectra and assayed its activity, result: The conformation of magnetized catalase changed to a certain extent, which led to y=210-310nm ultraviolet differential spectra and variation of fluorescence intensity at y=330 nm emission peak; The activity increased as well with the conformational change, conclusion: Magnetic effects of enzymatic molecular might be the key cause that resulted in organism biological effects.
