1.8.4.7	additional information	other disulfide compounds are either inactive or far less active than oxidized glutathione, reduction of disulfide bonds in ricin, thioltransferase activity, GSH:insulin transhydrogenase activity	89	
1.8.4.7	[xanthine dehydrogenase] + oxidized glutathione	reverse conversion possible by dithioerythritol, not obtained in presence of GSH	260398	
1.8.4.7	[xanthine dehydrogenase] + oxidized glutathione	conversion into oxidase by treatment with proteolytic enzymes, storage at -20°C/-25°C or preincubation with either thiol reagents or whole liver homogenate. Can act in the opposite direction in the reduction of the disulfide bond of insulin and ricin	260398
