Abstract:

In this manuscript,effect of the extremely low frequency alternating magnetic field on the specific and relative activity of catalase was investigated. The results suggested that magnetic field intensity,frequency and pH would generally decrease the specific and relative activity with the treatment time. But temperature changed specific and relative activity in a different way. The relative activity increased dramatically in the temperature of 55 ℃,reaching 2 142.86% at the time of 4 hours which was the highest point. According to circular dichroism(CD) results,the number of α helix and β fold in 25 ℃ magnetic field treatment was less than the control group,but the result was opposite in 55 ℃,which indicated that catalase might form a relatively resistant to high temperature structure.
