Abstract
Recent experiments have revealed that Ca2+ -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 phosphorylation 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 homogeneous 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.
