Recent experiments have revealed that Ca 2þ -calmodulin dependent myosin light chain phosphorylation in a cell-free preparation exhibits unexpectedly high sensitivity to weak magnetic fields. This enzyme system is a well-studied biochemical system, which appears to depend upon ion binding. A previous article in this journal discussed the theoretical background of myosin phosphory-lation and the ion-dependent interactions of EMF with soft tissues. Because of the electromagnetic field (EMF) sensitivity of this cell-free system, experiments were designed to test the effect of a pulsed radio frequency (PRF) field, pulsating magnetic fields (TEMF), gradient magnetic fields (Magnabloc), and homoge-neous static magnetic fields (in Helmholtz arrangement) designed for clinical application. It is concluded that these various magnetic fields affect this cell-free enzyme system by modulating ion–protein interactions.
