The enzymic oxidation of glutathione in rat liver homogenates.
1. The aerobic oxidation of GSH and other thiols by rat liver homogenate is abolished either by previous dialysis or by removal of the proteins but is restored by a mixture of the protein-free filtrate and the dialysed homogenate. 2. The oxidation is prevented by previously heating the dialysed homogenate but not the protein-free filtrate and also by known inhibitors of xanthine oxidase. 3. A similar oxidation occurs with hypoxanthine in place of of protein-free filtrate.
