Glutathione reductase scheme

Figure 1 A hypothetical scheme to illustrate the Tietze reaction. DTNB is represented as < >SS(t> and reacts with GSM to form the mixed disulphide GSS< >. This appears to be a substrate for glutathione reductase and is reduced to regenerate GSM, which then enters another round with DTNB, continuing to produce the yellow anion TNB at a rate that is dependent on the initial concentration of GSM.

It has been known for some time that there exists a close correlation between the ascorbic acid and glutathione content of plant tissues. Plant tissues are also known to contain dehydroascorbic reductase, which catalyzes the transfer of hydrogens from GSH to dehydroascorbic acid, as well as ascorbic acid oxidase. Mapson and Goddard have, therefore, provided a possible scheme for hydrogen transport which does not involve the cytochrome system. The hydrogens may take the following pathway ... [Pg.392]
