Effect of 50 Hz electromagnetic fields on acid phosphatase activity


K. S. Prashanth *, T. R. S. Chouhan and Snehalatha Nadiger

The effect of extremely low frequency (ELF) electromagnetic field (EMF) (50 Hz 0.5 mT) on the activity of acid phosphatase (EC was studied. In addition the factors affecting the enzyme activity such as the temperature, pH and substrate concentration were also investigated. The results show that ELF EMF have significant influence on enzyme activity. Upon EMF exposure Km increased from 0014 ± 0.005 to 0.040 ± 0.008 mM whereas Vmax increased from 0.991 ± 0.254 to 1.638 ± 0.345 µmol/min. Further studies can probably help in finding suitable applications for ELF based modulation of enzyme activity.
