Abstract
Magnetical effect to enzyme activity of immobilized catalase or peroxidase was examined by an electrochemical method. In buffer solution contained 10mM H202, oxidation current on an enzyme-immobilized-electrode (φ=0.1mm platinum-black electrode) was monitored under static strong magnetic fields. We observed increase of current with catalase-immobilized-electrode under 8 T. It means that immobilized-catalase-activity was disturbed magnetically. On the other hand, magnetical disturbance of immobilized-peroxidase-activity was extremely small under 14 T. From these results, we conclude that a catalase differs from a peroxidase in magnetical disturbance of immobilized-enzyme-activity.
