Abstract:
The results of spin chemistry studies of the single electron transfer step and the role of spin states of paramagnetic intermediates in the enzymatic oxidation of organic substrates induced by horseradish peroxidase are generalised. Detailed theoretical description of the approach used to analyse the magnetic field effects in enzymatic multispin systems is presented. Prospects for the use of spin chemistry techniques for elucidation of the mechanisms of radical steps of enzymatic processes are considered.
