Exposure to a 900 MHz electromagnetic field affects the catalytic activity of lactoperoxidase and horseradish peroxidase.

Plain English Summary

Summary written for general audiences

The study examined the effects of 900 MHz electromagnetic field exposure on the catalytic activity of lactoperoxidase and horseradish peroxidase. Experimental evidence indicates that irradiation causes conformational changes of the active sites and influences the formation and stability of intermediate free radicals, as shown by enzyme kinetics, circular dichroism spectroscopy, and cyclic voltammetry.
