Аннотация:The rate of a chemical reaction can be sensitive to the isotope composition of the reactants, whichprovides also for the sensitivity of such “spin-sensitive” reactions to the external magnetic field. Herewe demonstrate the effect of the external magnetic field on the enzymatic DNA synthesis togetherwith the effect of the spin-bearing magnesium ions (25Mg). The rate of DNA synthesis monotonouslydecreased with the external magnetic field induction increasing in presence of zero-spin magnesiumions (24Mg). On the contrary, in the presence of the spin-bearing magnesium ions, the dependenceof the reaction rate on the magnetic field induction was non-monotonous and possess a distinctminimum at 80–100 mT. To describe the observed effect, we suggested a chemical scheme andbiophysical mechanism considering a competition between Zeeman and Fermi interactions in theexternal magnetic field.
