Abstract:
:Recently, Stock et al. (J. Biol. Chem. 261, 15915-15922 [1986]) described a model enzyme system composed of horseradish peroxidase, hydrogen peroxide, phenol, glutathione and styrene. This system forms glutathione-styrene conjugates. Glutathione radicals and carbon-centered radicals are intermediates in this process. In the present study, this model enzyme system was also shown to generate singlet oxygen, probably via a Russell mechanism. No singlet oxygen was generated in the absence of styrene. Thus, contrary to prior suggestions, the reaction of glutathione radical with oxygen to produce a thiyl peroxyl radical is not a significant source of singlet oxygen.
