Abstract

Abstract— It has been demonstrated that photoreduced methyl viologen is stable during a flash photolysis experiment if a proper anaerobic environment is maintained. Therefore a new class of potential electron donors can be introduced in the study of transient phenomena associated with intermolecular electron transfer of redox proteins. The transient redox kinetic parameters of the flavocytochrome c from the photosynthetic bacterium Thiocapsa roseopersicina are reported for the first time and compared to similar data published for other fiavoproteins from diverse sources using flavin‐type electron donors. The advantages of the photoreduced viologen based transient electron donor system are discussed.
