Alteration of Enzymic Electron Transfer reactions Induced by Microwaves Emitted by GSM Mobile Phone

摘要

Enzymatic activity and conformational features of bovine lactoperoxidase (LPO), ascorbate oxidase (AO) and laccase (LAC) are modified when aqueous solutions of these enzymes are exposed to the microwave field emitted by a mobile phone. Several kinetic and spectrophotometric measurements were carried out comparing native and irradiated samples of the same enzyme solution. Experimental data obtained demonstrate that mobile phone radiations alter the active site conformational state. It has been also proved that electromagnetic fields (EMFs) interfere with free radical intermediate species of the electron transfer enzymatic reaction, providing a considerable modification of the kinetic parameter K_m, V_m and k_CAT
