用荧光光谱法研究了在不同磁场强度、温度、介质和磁化时间下,磁场对乳酸脱氨酶、肌酸激酶、尿酶、超氧化物歧化酶构象的影响。发现磁场能影响酶的构象,但光谱变化与酶活力变化无一定规律,并对其可能的作用机制和原因作了初步探讨。
The effect of magnetic field on the conformation of lactate deaminase, creatine kinase, urease and superoxide dismutase under different magnetic field intensity, temperature, medium and magnetization time was studied by fluorescence spectroscopy. It is found that the magnetic field can affect the conformation of the enzyme, but there is no regularity between the change of the spectrum and the change of the enzyme activity. The possible mechanism and reason of the change are also discussed.
